Quitting weed and alcohol might feel like a massive lifestyle shift, but your body starts rewarding you quicker than you’d think. Two weeks in, you’re already experiencing changes that’ll make you wonder why you didn’t do this sooner. Around 2.5 million Brits smoke cannabis each year, whilst over 200,000 take part in Dry January. Clearly, giving up these substances is on plenty of people’s minds.

The First Fortnight without Substances

When you stop using cannabis and drinking, your body kicks into repair mode almost immediately. That foggy feeling you’ve been blaming on late nights? It starts lifting within days when you’re giving up alcohol and weed.

Lauren Booker, an alcohol consultant, reckons the changes are noticeable pretty quickly. “Your brain fog might be wearing off, and you may find it easier to get up in the mornings,” she explains. Turns out, giving up alcohol does more than just save you from weekend hangovers.

What Happens inside Your Body When Quitting Weed and Alcohol

Professor Kevin Moore from University College London Medical Centre doesn’t mince words: stopping drinking for a month shifts liver fat, cholesterol and blood sugar levels, whilst helping you shed weight. “If someone had a health product that did all that in one month, they would be raking it in,” he said.

Recent research from Amsterdam tracked over 5,000 men across 44 years to understand what cannabis does to the brain. The findings? Surprising. Regular cannabis users showed minimal cognitive decline compared to non-users, just 1.3 IQ points difference on average. The study found no significant harmful effects on mental sharpness as people aged.

But that doesn’t give weed a free pass. The NHS warns that cannabis can worsen existing mental health symptoms and has links to anxiety, depression, and psychosis risks, especially with heavy use from a young age. Giving up cannabis matters for your mental health.

Physical Changes You’ll Notice

If acid reflux has been making your life miserable, the effects of quitting weed and alcohol bring relief within a fortnight. That burning sensation in your throat should be easing off by now.

Your mood swings? They’re settling down. When you’re giving up cannabis and drinking, you’re less prone to those emotional rollercoasters that come with regular use. Your brain chemistry gets a proper chance to rebalance itself.

And here’s something unexpected when quitting weed and alcohol together: you’re probably thirstier. “It’s not that you need more fluids than normal, just that you’re more in tune with just how much you do need,” Booker says. When you stop drinking, your body’s natural hydration signals work properly again.

Why Giving Up Cannabis and Drinking Helps Your Fitness

Fancy hitting the gym? There couldn’t be a better time. Alcohol acts as a muscle relaxant, so regular drinking actively reduces muscle development. Once you start quitting weed and alcohol, those workouts might finally show results.

“If you’re not a regular exerciser but have been thinking about giving it a go,” Booker suggests, now’s your moment. Your body’s ready to actually build strength and stamina instead of fighting against what you’re putting into it.

“When Quitting Weed and Alcohol Doesn’t Feel Dramatic”

Not everyone experiences massive changes by week two, and that’s alright. How much you were using before matters, the same as your overall lifestyle. Of the 5,162 men studied in the Amsterdam research, 39.3 percent had used cannabis at least once, and 51.1 percent of those started before turning 18.

Dr Lade Smith, president of the Royal College of Psychiatrists, doesn’t hold back on teenage cannabis use: “When you start smoking with your mates at 14 or 15, you’re literally growing your brain in a cannabis soup.” Brain development carries on into your mid-twenties, which makes early substance use particularly risky.

For people who used heavily or started young, giving up cannabis and drinking takes longer to show benefits. But stick with it. The changes are happening whether you feel them yet or not.

Looking Ahead

Over 200,000 Brits participate in Dry January each year, and plenty discover that stopping drinking opens the door to questioning other habits too. Cannabis, cigarettes, excessive caffeine – your body appreciates every positive change you make.

The research suggests that whilst cannabis might not destroy your IQ as dramatically as once feared, combining it with alcohol creates a double burden on your body. The benefits of giving up cannabis and drinking together stack up fast: better sleep, clearer thinking, improved fitness potential, and genuine mental clarity.

Your liver, your lungs, and your brain are all built to heal themselves given half a chance. Two weeks is just the start. Think about what a month could do. Three months. A year. That’s when quitting weed and alcohol really shows what it can do for you.
