Parents relentlessly bemoan about the “olden days,” an era when everything was better. Right?

Apparently, marijuana might not qualify — depending on your outlook. In a study released earlier this spring, research labs discovered that cannabis potency has jumped tremendously since 20 or 30 years ago. What this means is that the level of THC, or the component that gives the brain the “high,” has increased by at least three times since two or three decades ago. THC levels now sit at almost 30%, and when compared to the 4% that was measured in the 1980s, the difference is distinct. The rise is accredited to the trend of cross-breeding strains in order to reach higher potency.

Though at first, it seems as though this increase in potency may be a good thing, it seems as though our parents may still have something to hold over us about the “good old days” being better.

Researchers are concerned that the swell in potency may lead to unpredictable effects. Especially, a higher amount of THC may mean a greater risk of addiction for frequent users.
