Don’t know where you get your facts from but lots of “studies” are funded by big beer companies that have a lot to lose if cannabis were legalized.
People make a big deal about THC being much higher in the cannabis grown today. It’s like comparing booze to beer. I can drink three light beers compared to one whiskey sour. No need to smoke the same quantity as back in the day.
No, these were studies by NIH and other health oriented organizations.
You like dope? Fine. Keep ignoring the facts, it becomes easier to ignore them the more you smoke.
I smoked 1967-1970. Not daily, either; then one time in the early 80s I smoked two hits and I was amazed how much more potent weed had gotten. Two hits got me totally wasted in early 80s. I have read about the massive increase in THC and what it does to people. Large studies, a good one from Australia in which thousands of people were studied for decades.
Keep toking, have fun, say good bye to the ability to think rationally, etc.
