The study authors consider high-potency cannabis to be products with more than 10 percent tetrahydrocannabinol or THC, the compound responsible for the drug's psychoactive effects. The fact that consuming high-THC cannabis products has a greater risk is concerning, Lisdahl says, because these products are more common in the market now.
Now a new study published Tuesday [6]in the The Lancet Psychiatry shows that consuming pot on a daily basis and especially using high-potency cannabis increases the odds of having a psychotic episode later.
