And many, in my opinion, do more harm then good. Like the flu shot for example. I haven't had one in years and haven't been sick since while everyone I know that has taken it gets sick. I'm thinking certain drugs actually kill your immune system or maybe I'm just a freak of nature and have an extreme;y strong immune system. Who knows.
Marijuana can also be used for people with ADD and is more probable to do a better job then say ritalin...
life as we know it is impossible on venus, but life as we don't know it could be anywhere.
