Cannabis (Marijuana) with microscope in laboratory research. © Puntasit Choksawatdikorn | 123rf.com
There seems to be a growing consensus on the medical and mental health concerns associated with smoking marijuana. Beginning in the summer of 2007, a series of research studies into the health risks of smoking marijuana began to appear in medical and research journals. Several of these are summarized here for your convenience. I will periodically update this synopsis of research findings as new studies on marijuana are made public. This was last updated in December of 2019.
