According to a report, cannabis users risk psychosis depending on potency of the cannabis and how frequency they used it.
A study by King's College London scientists found smoking potent cannabis was linked to 24% of new psychosis cases. Psychosis are delusions or hallucinations that are usually associated with psychiatric conditions such as bipolar disorder and schizophrenia.
Scientists found the risk of psychosis was also five times higher for those who use cannabis every day compared to people who did not use cannabis at all.
According to the report, those using cannabis with high concentrations of THC, the main psychoactive ingredient in cannabis, such as Skunk are more susceptible to psychosis.
Interestingly, the report suggests hashish, cannabis resin, contains significant amounts of another chemical called cannabidiol or CBD that can act as an antidote to THC and counteract its psychotic effects.
The report suggests that users of potent "skunk-like" cannabis have a three times higher risk of psychosis than non-users.
