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.
Do I like dope? I like freedom and not a nanny state telling me I can't grow a plant or consume a drug that is far less harmful than alcohol. I laughed when you mentioned Australia - one of the most restrictive countries concerning cannabis use. The Aussie government sets up road blocks and swabs drivers mouths. It's a $2000 fine if you don't pass even though you may have consumed once weeks prior. As I mentioned in an earlier post, it's about money. The DEA, local law enforcement, jailers, pharmaceutical and alcohol manufacturers all stand to lose a lot of money if cannabis laws are overturned. It's only because of budget deficits that states are overturn prohibition.
The
NIH has finally admitted that there "may" be benefits to cannabis use such as suppressing cancer growth. But, because it's so difficult to get permission to study the drug due to pharmaceutical lobbiest, very few studies can be conducted. A doctor in Arizona lost her job in an attempt to study the effects of cannabis in treating PTSD.
Here's what I found on the NIH
website concerning IQ:
For example, a study showed that people who started smoking marijuana heavily in their teens and had an ongoing cannabis use disorder lost an average of eight IQ points between ages 13 and 38. The lost mental abilities did not fully return in those who quit marijuana as adults. Those who started smoking marijuana as adults did not show notable IQ declines.
As I mentioned in an earlier post, teenagers should not be using it. There appears to be no evidence that it rots the brains of adults.
