As medical cannabis, high THC vapes, and potent extracts become increasingly common in the UK, more people are searching for clear answers about symptoms they experience when reducing cannabis use.
Two topics come up often: cannabis withdrawal and Cannabinoid Hyperemesis Syndrome CHS.
Although the two can appear similar, they are not the same condition.
This UK focused guide explains the difference between cannabis withdrawal and CHS, how each one presents, why they happen, and what people generally do to manage the experience.

Cannabis withdrawal refers to temporary physical or emotional symptoms that some individuals experience when they reduce or stop using THC after long periods of frequent use.
THC affects the brain’s reward and endocannabinoid systems, so reducing intake can lead to short lived discomfort as the body adjusts.
Common cannabis withdrawal symptoms include:
These symptoms are usually mild to moderate and last for several days to a couple of weeks.
They do not typically cause repeated vomiting or require emergency medical help.
CHS is a separate condition believed to affect a small percentage of long term, heavy THC users.
The hallmark symptom is cyclical vomiting that does not improve until THC use fully stops. Hot showers often provide temporary relief.
CHS symptoms may include:
Unlike withdrawal, CHS can appear even if the person continues using THC. Symptoms typically improve only after full abstinence.
Withdrawal usually presents with emotional or routine related discomfort, while CHS is dominated by vomiting and stomach pain.
Withdrawal begins after reducing THC intake. CHS symptoms can appear while still using THC daily.
Withdrawal tends to be short lived. CHS symptoms can continue until THC is completely discontinued.
Withdrawal gradually improves as the body adapts. CHS relief is strongly associated with stopping THC and sometimes hot showers.
Because THC potency has increased, more people are experiencing withdrawal symptoms than in previous decades.
CHS appears far less common but is increasingly recognised by UK clinicians as daily high THC vaping and extract use becomes widespread.
Both involve changes in how the body reacts to THC. People sometimes assume their nausea is withdrawal, especially if they have just cut back, when the pattern may actually fit CHS.
Others may believe CHS symptoms are caused by tainted products or anxiety rather than high THC exposure.
People in the UK generally focus on short term lifestyle support such as:
Some individuals use CBD oils or CBD vape products as part of their transition away from THC.
