Today’s cannabis contains, on average, much higher concentrations of THC, the main component responsible for its psychoactive effects. And this changes its risk profile.
The higher the concentration of THC, the greater the likelihood of experiencing anxiety, panic, tachycardia, paranoia, or even psychotic symptoms during intoxication. In addition, when consumption is frequent, especially daily, high-potency products have been associated with an increased risk of dependence and mental health problems.
This does not mean that everyone will suffer these consequences, but it does mean that the risk increases. And it does not depend only on THC: the dose, frequency of consumption, age of onset and vulnerability of each person also play a role.
