THC is the only cannabinoid with any intoxicating punch, and it’s long been demonized as risky, if not outright dangerous. Because of these long-standing assumptions, some are calling for THC caps as a means to reduce this risk.

There are already specific limits on THC in Canada: 10 milligrams per edible package and 1000 milligrams per extract package. States like California and Colorado have similar per-package limits (although typically much higher). But, in Vermont’s soon-to-open adult-use market, there will be a potency cap on the THC in flower. Florida, New York, and even federal regulations may follow suit.

Is THC truly dangerous, though? And if so, will any of the current or proposed restrictions work for their intended purpose?

Dr. M-J Milloy, PhD, Research Scientist at the British Columbia Centre on Substance Use (BCCSU) and an assistant professor in the Department of Medicine at the University of British Columbia (UBC), has a few opinions on both the current and proposed THC caps…
