Pretty weak sauce in that article, if you ask me.
For example, the first thing in the list - who thinks that today’s weed is weak? Everyone knows that it’s actually very strong now compared to the “ditch weed” often available in the 60s or 70s, although there was also some very good stuff around back then, I’ve read. Actually, it’s the drug warriors who always trot out how potent today’s weed is as an argument against it, while I’ve never heard anyone claim that today’s weed is weak. Rum is a lot stronger than beer, too, but I don’t necessarily get any drunker from rum than beer.
And on the alcohol-pot comparison, it’s true that while alcohol can be consumed without intoxication, even relatively small amounts (like one beer or glass of wine) do have an effect on the mind and body. Some people consume pot in very tiny quantities, too, for a mild calming effect. As to the health effects of chronic use (i.e. addiction/alcoholism), alcohol is far, far worse.
Myth #5’s answer sounds like the perfect argument by nanny-staters for government intervention into all aspects of our private lives. People do many, many things that might (might) cause some “private self-damage that always leaks out into the public sphere”.
And actually, the whole article has a puritanical feel about it - many, many people enjoy occasionally getting intoxicated on one substance or another, and yet still lead productive lives. It’s called having fun (in our opinions), not a sign of some deep emotional or psychological problem.
It’s a lot stronger than the crap in the 70’s. More expensive too.
