The First Week: Your Hour-by-Hour Quit Timeline

The Text I Sent at 3am

Day 2. 3:17am. Wide awake, heart racing, staring at the ceiling.

I picked up my phone and texted Dave: "Is this normal? Feel like I'm dying."

He replied at 3:19am (because Dave is also an insomniac): "Yeah mate. Night 2 was the worst for me. It passes. Don't do anything stupid."

This is the article I wish I'd had that night. The hour-by-hour breakdown of what happens when you quit tobacco but keep using cannabis — via a dry herb vape instead of spliffs. What's normal. What's temporary. What's your brain lying to you.

Because here's the thing nobody tells you: the research on this specific scenario barely exists. There are thousands of studies on quitting cigarettes. There are studies on quitting cannabis. There are even studies on people who use both. But "UK spliff smoker switches to dry herb vape, quits tobacco, continues cannabis"? That's us. That's the thing we're actually doing. And the science hasn't caught up yet.

So this article is part research, part lived experience, part "what Dave and Tom and I figured out the hard way." Jake's in here too, but Jake's story is mostly a cautionary tale, which I'll get to. Your mileage may vary. But at least you won't be staring at the ceiling at 3am wondering if you're the only one.

The Weird Thing About Quitting Spliffs

Let me explain why this is different from every other "quit smoking" article you've read.

When you smoke spliffs the UK way (70–80% tobacco, 20–30% cannabis), you're addicted to both nicotine and the ritual of cannabis. Your brain has learned that these two things come together. But — and this is the bit most people miss, including me for about the first fortnight — you're probably blaming the wrong plant.

Most of the unpleasantness you associate with "weed" is actually tobacco dependency wearing the cannabis costume. The morning fog, the need to have one before work, the "something's missing" feeling at the pub — that's nicotine. Not weed. My mate Dave spent his first attempt convinced cannabis was trying to kill him. It wasn't. It was Amber Leaf.

When you switch to a dry herb vape, you're doing something strange: quitting nicotine (full withdrawal), continuing cannabis (but through a different delivery method), and keeping the ritual (inhale, exhale, take a break).

You're not quitting cold turkey. You're substituting. That's not cheating — that's harm reduction with a realistic understanding of how habits work.

— Dennis M.

This means your experience won't match the standard "quit smoking" timeline exactly. Some things will be easier (you still have the hand-to-mouth ritual, you still have cannabis). Some things will be harder (your brain is confused about why the nicotine isn't arriving with the THC anymore).

A 2023 study found that people with higher tobacco dependence had significantly worse cannabis withdrawal when they quit cannabis — suggesting the two substances interact in ways that make any kind of quit harder when both are involved. But here's the gap: nobody has studied what happens when you quit tobacco but keep cannabis. So I'm going to tell you what actually happened to me, cross-referenced with what the science says about nicotine withdrawal, and let you calibrate from there.

Day 0: The Last Spliff

I didn't quit on a Monday. I didn't wait for New Year's. I quit on a random Thursday in 2018 because I'd just bought a Mighty+ and I wanted to see if I could actually do this. I was 34, my GP had recently given me a polite-but-unmistakable nudge about my breathing, and I'd finally taken the hint.

The prep that helped:

1. Binned the tobacco. Not "put it in a drawer." Binned it. Wet it first so I couldn't fish it out later. (Yes, I've fished tobacco out of bins before. No judgement.)
2. Cleaned everything. Ashtrays, rolling trays, the little tobacco crumbs in my jacket pocket. The smell is a trigger. Remove it.
3. Loaded the vape. Had it charged, packed, ready to go. The new ritual needs to be easier than the old one.
4. Told Sarah. "I'm quitting tobacco. I'm going to be a nightmare for a week. I'm sorry in advance."

The ritual of smoking is almost as addictive as the nicotine itself. Research shows that maintaining a hand-to-mouth, inhale-exhale pattern helps people stay off combusted tobacco. A dry herb vape preserves that pattern while removing the tobacco.

Day 1: The First 24 Hours

Hours 0–2: The Honeymoon

Nothing. Felt fine. Actually felt optimistic. This is the trap.

For the first couple of hours, you've still got nicotine in your system. You haven't started withdrawing yet. Your brain is like "this is easy, why didn't we do this sooner?" The danger: this is when people think "I've got this" and skip the preparation. You haven't got anything yet. The nicotine just hasn't worn off.

What I did: used my vape. Twice. Just to establish the new pattern. "This is what we do now. This is the ritual."

Hours 2–8: The First Cravings

Around hour 3, the first real craving hit. Not overwhelming — just a background itch. A thought that kept returning: "A spliff would be nice right now."

By hour 6, I was irritable. Sarah asked me a normal question about dinner and I snapped at her. Then immediately apologised. Then felt guilty about snapping. Classic early withdrawal emotional rollercoaster.

The science: nicotine has a half-life of about 2 hours. By hour 4–6, blood nicotine levels have dropped significantly. Your brain notices. It sends craving signals. This is the beginning.

What helped: water (so much water — I drank 3 litres on Day 1), structured distractions (cleaned the kitchen, then the bathroom, then reorganised my desk drawer), and the vape (every time I thought "spliff," I used the vape instead — different hit, same ritual).

Hours 8–24: Sleep Disruption Begins

Went to bed at 11pm, feeling okay. Woke up at 2am. Wide awake. Heart beating faster than normal. Took an hour to fall back asleep. Woke again at 5am. This time with a headache. Gave up on sleep, made tea, sat in the kitchen feeling sorry for myself.

The science: nicotine affects your sleep architecture. When you remove it, your brain goes through adjustment. The classic "3am wake-up" is partly about nicotine's stimulant effects wearing off overnight (your brain expects a hit that isn't coming) and partly about cortisol rhythm disruption. Also: more vivid dreams, because nicotine suppresses REM sleep and without it, REM rebounds. Some people find this interesting. I found it unsettling — I dreamed about my teeth falling out, which apparently is a stress dream.

What helped: accepting it was temporary, not looking at my phone at 2am, and tea, not coffee. Caffeine makes everything worse in Week 1 (more on this in a minute).

Days 2–3: Peak Withdrawal

This is the worst of it. Nicotine withdrawal typically peaks between 24–72 hours after your last cigarette (or spliff).

What you'll likely feel: strong cravings (10–20 per day, lasting 3–5 minutes each), irritability (everything is annoying, everyone is annoying), free-floating anxiety, difficulty concentrating, mild headaches, and increased appetite (nicotine suppresses hunger; now it's back).

For ADHD Brains Specifically

This is where it gets rough. I have ADHD. I take Elvanse (lisdexamfetamine). And Day 2–3 was significantly harder for me than for Tom, who doesn't have ADHD.

Here's why: ADHD brains already have lower baseline dopamine. Nicotine temporarily boosts dopamine, which is why so many people with ADHD smoke — it's accidental self-medication. When you remove nicotine, your dopamine drops even further. Your ADHD symptoms get worse. Focus is shot. Emotional regulation is gone. Rejection sensitivity goes through the roof.

Research confirms this: people with higher ADHD traits report significantly greater withdrawal severity. The good news? ADHD medication can help buffer this. Studies show that stimulant meds reduce withdrawal symptoms and improve concentration during abstinence.

So if you're on ADHD meds: take them consistently during Week 1. They're not undermined by quitting nicotine — if anything, they're more important because they're partially compensating for the dopamine you just lost.

Day 2 Morning: The Wall of Irritability

Woke up angry. Not at anything. Just angry. Sarah made breakfast. I complained about the eggs. (The eggs were fine.) Tried to work. Couldn't focus for more than 10 minutes. My brain felt like it was wrapped in cotton wool — but angry cotton wool.

Day 2 Afternoon: The Coffee Revelation

I made coffee at 2pm. Normal routine. Within 20 minutes, I was jittery, anxious, and had the strongest craving I'd experienced yet.

Here's what I didn't know: nicotine speeds up caffeine metabolism. When you quit nicotine, the same amount of coffee hits you harder because your body isn't clearing it as fast. So my normal 2pm coffee was suddenly like a double espresso. And the jitters felt like craving. And the craving made me want a spliff.

What I did: switched to half-caff, then to tea. By Day 4, I was back to coffee, but I kept the dose lower for the first two weeks. Tom didn't believe me about this until he experienced it himself. "I thought I was having a panic attack," he said. "Turns out I'd just had three coffees and zero nicotine."

Day 3 Evening: The "Just One" Voice

Day 3 evening. Sarah was out. I was alone with my thoughts.

My brain said: "You've done three days. You've proved you can do it. One spliff won't hurt. You can quit again tomorrow." This is the voice. Everyone hears it. It sounds reasonable. It is lying.

Even a single cigarette after several days of abstinence rapidly re-stimulates your nicotinic receptors. Your brain encodes this as massive relief — "YES, finally, the thing we needed!" — and the old addiction pathway lights up immediately. Then comes the "abstinence violation effect": the psychological spiral where you think "I've blown it, might as well smoke properly now."

"The 'just one' thing is bollocks," Jake told me later. "Your brain is lying. It's not one. It's never one. Also the TinyMight was a very expensive way to learn that."

What I did that Day 3 evening: messaged Dave. He talked me down. Then I used my vape, watched a film, and went to bed early. Not heroic. Just getting through.

Days 4–5: The Wall

By Day 4, the acute physical withdrawal is starting to ease. But something else takes over: habit and trigger cravings. The physical need is fading. But your brain still expects nicotine in certain contexts: after meals, with coffee, when stressed, when bored, after sex (yes, this is a real trigger — nobody talks about it, but it's very real), evening wind-down.

These aren't chemical cravings. They're Pavlovian. Your brain learned that "finish dinner → smoke." Now dinner ends and your brain screams for the missing step.

How to tell the difference: chemical cravings have physical features (tight chest, restlessness, "I need it NOW" urgency); they peak early (Days 1–3) and fade. Habit cravings occur in specific contexts and can be defused by changing the environment or activity. They feel more like "something's missing" than "I'm dying."

Day 4: The After-Meal Craving

Finished lunch. Immediately wanted a spliff. Not desperately — just automatically. My body started moving toward the back door before my brain caught up.

What I did: used the vape instead. Then went for a walk. Changed the context. This is where the dry herb vape really helped. The ritual is similar enough that my brain accepted it as "the thing we do after food." Different substance, same pattern.

Day 5: The Boredom Trap

Weekend. Nothing planned. By 2pm I was climbing the walls. Boredom is a massive trigger. Smoking fills time. It gives you something to do with your hands. It's a micro-break from whatever you're avoiding. Without it, you suddenly have all these empty minutes.

I made a list of 10-minute activities. Things I could do instead of smoking: walk around the block, make tea (I drank more tea in Week 1 than in my entire 20s), do 10 press-ups, text Dave or Tom, use the vape, clean something obsessively (the kitchen was spotless by Day 6).

Days 6–7: Turning a Corner

By Day 6–7, most people start to feel human again.

Physical improvements: breathing feels easier (cilia waking up, airways relaxing), energy coming back (oxygen levels normalising), sleep improving, coughing may increase (this is good — your lungs are clearing out).

Mental improvements: cravings less frequent (maybe 5–10 per day instead of 20), each craving shorter and less intense, you can concentrate for longer stretches, the irritability is fading.

What's still hard: surprise cravings, social situations (if your mates still smoke spliffs), the "just one" voice (it gets quieter, but it doesn't disappear).

Day 7: The First Real Breath

I was walking to the corner shop. Not fast. Just normal pace. And I noticed I wasn't out of breath.

This sounds minor. But for the past few years, even mild exertion left me slightly winded. I'd normalised it. "I'm just unfit." Day 7, I walked to the shop and back without thinking about my breathing at all.

The Weird Symptoms Nobody Warns You About

The standard "quit smoking" advice mentions cravings, irritability, and sleep problems. Here's what they don't mention.

Constipation

Days 2–5. Nicotine stimulates bowel motility. Remove it, and things slow down. I didn't poo for three days. Then I panicked and ate an entire bag of dried apricots. This was a mistake. What helps: fibre, water, movement. It resolves by Week 2.

Mouth Ulcers

Days 3–7. Small, painful ulcers appeared inside my cheeks and on my tongue. The exact mechanism isn't fully understood, but it's thought to involve immune rebound and changes in oral flora now that smoke isn't suppressing everything. What helps: salt water rinses, avoiding acidic foods, time. They cleared up by Week 2.

Tingling in Hands and Feet

Days 2–4. Weird pins-and-needles sensation, especially in the morning. This is your circulation improving. Blood is getting to places it was struggling to reach. Feels strange but it's actually good.

Dizziness

Days 1–3. Light-headed, especially when standing up quickly. Oxygen and carbon monoxide levels are normalising. Blood pressure is shifting. Usually transient and benign. When to worry: if dizziness is severe, persistent, or accompanied by chest pain, see a GP.

Increased Appetite (Beyond "Oral Fixation")

Nicotine suppresses appetite and raises resting metabolic rate. When you quit, both reverse. You're significantly hungrier, and you burn slightly fewer calories at rest.

The Cough Gets Worse Before It Gets Better

Days 4–10. You may cough more than you did while smoking, and bring up brown or grey mucus. This is your cilia waking up and clearing out accumulated tar. It's gross but it's healing. (I covered this in detail in Your Lungs After 30 Days Smoke-Free.)

The ADHD Survival Guide (What I Wish I'd Known)

If you have ADHD, Week 1 is harder. Here's what helped me.

1. Take Your Meds Consistently

This isn't the week to forget doses or experiment with timing. Your brain is already down on dopamine from nicotine withdrawal. Your meds are compensating. Research shows ADHD medication reduces withdrawal symptoms and improves concentration during abstinence. Use them.

2. Pre-Plan Everything

Executive function is shot during withdrawal. You can't rely on "I'll figure it out in the moment." Write down: what you'll do when cravings hit (specific actions, not vague intentions); who you'll text if you're struggling; what your vape schedule looks like; what you'll eat (decision fatigue is real).

3. Warn People

"I'm quitting tobacco and I have ADHD. My emotional regulation is going to be worse than usual for a few days. I'm not trying to be difficult." I sent this to Sarah, my manager, and Dave. It helped. People gave me more grace when they understood what was happening.

4. Expect the Dopamine Crash

Days 2–3, I felt flat. Not sad exactly — just grey. Nothing was interesting. Nothing was rewarding. This is the dopamine crash. Nicotine withdrawal reduces basal dopamine in the same brain circuits that are already compromised in ADHD. It passes. By Day 5–6, things started to feel interesting again.

5. RSD Will Be Worse

Rejection Sensitive Dysphoria — that ADHD thing where perceived criticism feels like being stabbed — gets worse during withdrawal. I nearly cried because Sarah suggested I was loading the dishwasher wrong. Not a proportionate response. Know it's coming. Warn your people. Forgive yourself.

When to Worry vs. What's Normal

Normal (unpleasant but expected): irritability, anxiety, low mood; poor sleep, vivid dreams, 3am wake-ups; increased appetite and weight gain; cough, mucus, tight chest; constipation, mouth ulcers, tingling; concentration problems; strong cravings (especially Days 2–3).

See your GP if: chest pain (sharp, persistent, or with shortness of breath); severe depression that doesn't lift; suicidal thoughts; dizziness that's severe or doesn't resolve; any symptom that feels "wrong" in a way you can't explain. Trust your instincts. If something feels medically concerning, get it checked.

Crisis resources: Samaritans 116 123 (free, 24/7, for anyone struggling emotionally); NHS Smokefree (search "NHS stop smoking services" for your local support); FRANK 0300 123 6600 (for questions about cannabis and other drugs). You can use NHS stop smoking services even if you're "only" quitting tobacco and continuing cannabis. They've heard it all. They won't judge.

The Cannabis Question

Here's the thing nobody in the research is studying: does continuing cannabis (via vape) make nicotine withdrawal easier or harder?

Arguments for "easier": you still have the ritual (inhale, exhale, break); cannabis may blunt some anxiety and sleep disruption; you're not quitting everything at once.

Arguments for "harder": cannabis can cause disinhibition, which might make "just one cigarette" more tempting (especially with alcohol); it's harder to track what you're feeling — is that cannabis? Nicotine withdrawal? Both? Your brain is confused about why the nicotine isn't arriving with the THC anymore.

What I experienced: the vape helped enormously with the ritual and the hand-to-mouth thing. But I had to be careful in certain contexts. Parties were danger zones. Cannabis plus alcohol plus being around people smoking? That's when the "just one" voice got loudest. I avoided parties for the first two weeks. Not forever — just until the acute withdrawal passed.

You're not quitting cannabis. You're quitting combustion. The plant's fine. The fire is the problem. Blame the right plant.

The Craving Trigger Cheat Sheet

Trigger	Why It Happens	What to Do Instead
After meals	Learned association + blood sugar changes + meal-completion reward	Use vape, short walk, brush teeth
With coffee	Pavlovian cue + caffeine feels stronger without nicotine	Switch to tea or half-caff for Week 1–2
Stress	Nicotine relieved stress by relieving withdrawal; brain reaches for old solution	Deep breaths, walk, vape, text someone
Boredom	Smoking filled time and gave you something to do	10-minute activity list, change environment
After sex	Big dopamine event + learned ritual + relaxation	Acknowledge it'll happen, have vape ready, no tobacco in the house
Evening wind-down	Nervous-system transition; cigarettes were the decompression tool	New wind-down ritual (vape, tea, walk, bath)
Alcohol	Disinhibition + social context + "just one" voice gets louder	Avoid or limit alcohol for first 2 weeks

What Week 2 and Beyond Looks Like

The detail gets sparser here because the experience does too. The drama of Week 1 fades into something quieter — less suffering, more adjustment.

Week 2: physical withdrawal mostly resolved; cravings continue but less frequent and intense; sleep improving; energy returning; still vulnerable to triggers and "just one" thinking.

Weeks 3–4: starting to feel normal; cravings are occasional, not constant; breathing noticeably better; may have moments of "why did I ever smoke?"

Months 2–3: new normal established; cravings are rare and easily dismissed; physical improvements continue; risk of relapse drops significantly (but never to zero).

I covered the physical recovery in much more detail in Your Lungs After 30 Days Smoke-Free. Research shows relapse risk is highest in the first weeks. Each day you don't smoke makes the next day easier.

The Thing I Didn't Expect

Here's what surprised me most about Week 1: I grieved. Not dramatically. Not crying into my pillow. But there was a genuine sense of loss.

Spliffs had been my companion since I was sixteen. My stress relief. My reward. My ritual. My friend. Quitting felt like losing something, even though I knew it was killing me.

That grief is real. You're allowed to feel it. You're allowed to acknowledge that tobacco gave you something, even as it took your health. The vape isn't a perfect replacement. It's different. But it gave me something to move toward instead of just something to move away from.

And now, years later, I don't miss spliffs at all. The grief passed. The ritual adapted. My lungs work again. I'm 42 with a mortgage, knees that forecast rain, and a strong suspicion that 10pm is a reasonable bedtime. None of that required spliffs. But in Week 1, I didn't know any of that. I just had to get through.

The One-Week Promise

Here's what I want you to know.

The first 72 hours are the worst. Peak withdrawal. Maximum suffering. Your brain at its most desperate. By Day 7, it's meaningfully better. Not perfect. But better. The acute phase is over. The physical symptoms are fading. You're through the worst of it.

One week. That's what you're committing to. Seven days of being uncomfortable so you can have years of breathing properly. It's not nothing. But it's not forever either. You can do a week.

And if you're reading this at 3am on Night 2, wondering if you're dying:

You're not dying. You're healing. It feels like shit because your brain is rewiring itself. Text someone. Use your vape. Drink some water. Don't make any decisions. Tomorrow will be marginally better. The day after, slightly better again.

One week. You've got this. And — one more time for the back — blame the right plant.
