One problem I came into when putting together the case studies with scientific evidence was the lack of good testing in regards to marijuana addiction. A lot of studies don’t isolate marijuana away from other substances – that is to say, the junkie or addict didn’t JUST smoke marijuana. For the majority of my case studies though, that IS the case. Some of my stories from Marijuana Addiction Help, from forums, from guestbooks, and from people I met through my research contacts.
