I gave up smoking cannabis eight years ago. I’d been promoted – from Telemarketing Supervisor to the noble heights of Telemarketing Manager – and I couldn’t turn up with a head wrapped in cotton wool any more. My abiding memory of the ensuing week was a nightly stream of terrifying dreams. It was like I was dreaming in stereo, as my brain experienced the novelty of truly deep sleep for the first time in years.
And then the dreams pretty much stopped. Within a week, once the night terrors and the cold sweats had desisted, my short-term memory started to improve. I had more energy. I was more sociable in and outside work. I left the job within a few months and started doing something I loved. Everything about my life improved. But giving up weed isn’t so easy for everyone, and for some it’s fraught with acute problems – physical, mental and emotional.
"Stopping my consumption of cannabis used to mean a lot of pain, vomiting, diarrhoea and not being able to sleep or eat," says Alex Fraser, 26. Alex has Crohn’s disease, which was diagnosed when he was 19. He just had an an ileostomy, in which a diseased part of his bowel was removed. This has drastically improved his quality of life, but he’s still hugely reliant on cannabis to keep his motor running.
"Despite the surgery, I still have issues with eating, nausea and sleep," he says. "If I don’t have cannabis, I end up using Pharma meds: zopiclone for sleep and oxycodone for pain. But nothing particularly helps my nausea or appetite, except cannabis."

Alex, who generally vapes but occasionally smokes and eats marijuana, also relies on it to keep his mental health in check. "It’s extremely helpful with the mental health issues I’ve had since surgery. Anxiety attacks, self-esteem issues and energy levels are all improved or eliminated with cannabis," he explains.
Jon Liebling is a Director of the United Patient’s Alliance, which is currently lobbying hard for the legalisation of medical weed in the UK. Jon has a long history of profound mental health issues and has recently been diagnosed with complex PTSD.
"I've been managing my anxiety, depression and suicidal thoughts most of my life, but have kept myself relatively happy with the use of cannabis," says Jon. "About two years ago, I had a number of traumatic events take place in a rather short space of time. I realised I needed a bit more help, so I asked my doctor to refer me for talking therapy. When I informed him I used cannabis he refused to refer me unless I stopped using. He prescribed me prozac and diazepam. I’ve always had suicidal thoughts, but what’s kept me alive is my dissatisfaction with them. Prozac made my thoughts happier, but also made me happier with those suicidal tendencies. So I acted on them for the first time in 20 years."
Jon went back to the doctors and found that a locum was working that day. She immediately removed him from his prozac prescription and referred him to talking therapy. She also told him to return to managing his condition with cannabis, and he’s thankfully still here to tell the tale.
Unfortunately, beyond anecdotal evidence it’s quite hard to back up Alex and Jon’s comments with science as, at the time of writing, there just isn’t much out there. Plus, their personal health conditions – despite being undoubtedly severe – are not indicative of the population as a whole. A 2010 paper called "Assessment and management of cannabis use disorders in primary care" suggests that, to differentiate between a psychiatric disorder and chronic cannabis intoxication, a patient should cease cannabis use for two to four weeks. In a small 20-person impatient study of withdrawal it found that "mean baseline depression symptom scores reduced to normal levels after four weeks of abstinence".
One of the study’s creators was Professor Adam Winstock, founder of the Global Drug Survey – a study of how the world consumes drugs – and a Consultant Psychiatrist and Addiction Medicine Specialist. Between these two roles he’s analysed the drug-taking habits of approximately 500,000 people, and 300,000 cannabis users. He’s extremely well-placed to advise on dealing with the more established effects of cannabis withdrawal. For most people, as it was with me during my Big Promotion back in the mid-2000s, that means: a) insomnia and vivid dreams; and b) nicotine withdrawal. A huge part of the first problem comes from an unlikely source.
"Lots of people who smoke lots of weed drink too much caffeine. Tea, coffee, fizzy drinks, Red Bull. This is often to offset the sedating effects of their weed. If you keep drinking 15 cups of tea when you’ve given up weed, this is going to worsen your insomnia, which will make you agitated," says Winstock.

If you’ve grown up smoking spliffs with tobacco in them, there’s a good chance you will also experience cravings from the nicotine withdrawal. For those looking to give up weed, Adam advocates giving up cannabis and nicotine at the same time – but adds that, crucially, you should gradually reduce your tobacco intake in the run-up to quitting. This will have an unexpected second benefit in the fight against withdrawal sleeplessness.
"Tobacco metabolises caffeine. It breaks it down," he explains. "So when you stop smoking tobacco, your caffeine levels go through the roof. You're left with this double whammy: not only taking a stimulant drug [caffeine] that you likely drink too much of anyway, but you're taking a stimulant drug whose levels are going to go through the roof because tobacco is no longer breaking it down."
Adam also says that the intensity of your withdrawal will likely be affected by the type of weed you smoke. "If you smoke a high THC cannabis, like skunk, then I think the insomnia would be worse – your weird dreams would be worse, your craving would be worse, your low mood would be worse."
Withdrawal symptoms with weed peak around day two or three and are generally over after seven. Sleeplessness and vivid dreams may last for two weeks, but Adam’s absolute gold standard advice for giving up is to "get into good sleep hygiene". Admittedly easier said than done, but there are some common sense habits that will help.
"Exercise is probably the best thing you can do," he says. "Obviously don’t over-exert yourself, but if you’re tired out when you go to bed, you’re much more likely to sleep well. Turn off screens a couple of hours before bed, avoid caffeine. And don’t give up and call your dealer if you get a bad night’s sleep! It will get easier soon."
