Anxiety after quitting weed

Many people smoke or vape weed to take the edge off, then find the edge comes back sharper when they stop. That is common, it is usually temporary, and there is a lot you can do about it.

The short version

• Anxiety is a recognised part of cannabis withdrawal in regular users. It is not a sign you are going mad or that quitting is a mistake.
• It usually starts within one to three days, peaks in the first one to two weeks and eases over several weeks.
• Poor sleep makes anxiety louder. Fixing sleep fixes a lot of it.
• Panic attacks, thoughts of self-harm or anxiety that will not lift are reasons to see a doctor, not to tough it out.

Why it happens

Regular cannabis use changes how the brain's own cannabinoid system works, which is involved in stress, sleep and mood. When you stop, the system takes time to rebalance, and in the meantime your stress response can run hot. Add the loss of a tool you used to calm down, and the result is feeling wired, jumpy and on edge.

Other factors pile in. Sleep is usually disrupted, and a tired brain is an anxious brain. Appetite dips. If you were also using nicotine, or quitting that too, the effects combine. And for some people, cannabis was covering up an anxiety problem that was there first, so it becomes visible when the weed goes.

What it feels like

A racing mind, a tight chest, restlessness, sweaty palms, a short fuse, trouble concentrating, and sometimes a sense of dread with no clear cause. Mornings and late evenings are often the worst. It tends to come in waves rather than staying constant.

What helps

• Protect sleep first. Same wake time every day, no screens in bed, no caffeine after midday, and a cool dark room. See our guide on sleep and vivid dreams.
• Move daily. A brisk 20 to 30 minute walk lowers tension and helps sleep. Exercise is one of the best-supported ways to ease anxiety.
• Slow your breathing. Breathe in for four, out for six to eight, for two to five minutes. A longer out-breath calms the body's alarm response.
• Cut caffeine. Coffee and energy drinks mimic anxiety. Halve your intake for the first fortnight.
• Eat regularly. Skipped meals and low blood sugar feel like anxiety. Small, frequent meals work even when appetite is poor.
• Name it. "This is withdrawal anxiety, it peaks and passes" takes some of the fear out of it. Fear of the feeling feeds the feeling.
• Plan the trigger times. If you smoked to wind down at night, put something else in that slot: a shower, a walk, a call, a show.
• Talk to someone. One person who knows what you are doing is enough.

What to avoid

Alcohol as a substitute. It feels calming for an hour and then worsens anxiety and sleep. Swapping weed for more nicotine or energy drinks does the same. And "just one" to settle down usually resets the clock.

When to see a doctor

• Panic attacks, or anxiety that stops you working, sleeping or leaving the house.
• Thoughts of harming yourself or feeling hopeless. Get help the same day, from a doctor, a crisis line or emergency services.
• Anxiety that is not improving after about four weeks.
• You had anxiety, depression or another mental health condition before cannabis.
• Hallucinations, paranoia or confused thinking.

A doctor can screen for an underlying anxiety disorder and offer options such as cognitive behavioural therapy or medication where suitable. Treating it directly usually removes the main reason to go back to cannabis.

What to expect

Week one is the roughest. By week two many people notice the waves are shorter and further apart, and by week four sleep and mood are generally steadier. It is rarely a straight line: good days and bad days alternate. A bad day in week three is not failure, it is the pattern.
