a) Virtually all the links you posted are from newspaper articles
b) There are Olympians and pro athletes who smoke tobacco, drink alcohol and do all kinds of unhealthy things. Does it make those things great?
It's incredibly stupid reasoning to give an example of one person that is able to accomplish something and somehow relating it to pot. Similar idiotic reasoning to claim smoking is fine since you can see a 90 year old guy smoking. Stop embarrassing yourself and at least support some of your nonsense from studies from reputable universities or medical organizations instead of an article in Time or the SCMP.
As to contributions, you're basically acting as a drug pusher and making claims that remind me of chiropractors trumpeting they can cure a cold with manipulations.
Here's another one of these "old" articles from a little unknown place called Harvard:

The psychiatric risks are well documented, and include addiction, anxiety, and psychosis.
Inhalation is the fastest way to deliver THC to the bloodstream, which is why patients may prefer smoking an herbal preparation. But while this method of drug delivery works fast, smoking marijuana exposes the lungs to multiple chemicals and poses many of the same respiratory health risks as smoking cigarettes.
More psychiatric risk than benefit
Addiction. Observational studies suggest that one in nine people who smokes marijuana regularly becomes dependent on it. Research both in animals and in people provides evidence that marijuana is an addictive substance, especially when used for prolonged periods.
The most commonly reported side effects of smoking marijuana are intense anxiety and panic attacks. Studies report that about 20% to 30% of recreational users experience such problems after smoking marijuana. The people most vulnerable are those who have never used marijuana before.
An Australian study that followed the outcomes of 1,601 students found that those who used marijuana at least once a week at ages 14 or 15 were twice as likely to develop depression seven years later as those who never smoked the substance — even after adjusting for other factors.
An often-cited study of more than 50,000 young Swedish soldiers, for example, found that those who had smoked marijuana at least once were more than twice as likely to develop schizophrenia as those who had not smoked marijuana. The heaviest users (who said they had used the drug more than 50 times) were six times as likely to develop schizophrenia as the nonsmokers.
When compared with controls, people who used medical marijuana were more likely to develop pneumonia and other respiratory problems, and experience vomiting, and diarrhea.
Studies suggest that although overall cognitive ability remains intact, long-term use of marijuana may cause subtle but lasting impairments in executive function.
Even if only half of those were true. What a wonderful thing to be pushing! So you want to tell people to listen to you instead of professionals from Harvard Medical School? Really?
You certainly have a leg to stand on if you argue that legalizing can have benefits in reducing crime and making the drug safer but it's irresponsible and plain stupid to make the kind of claims you make to try to further your goal of legalization.
