The Medicine of Cannabis


Out of curiosity, what are other peoples experience is in working with cannabis a a medicine to alleviate various symptoms or ailments? (Rx or not:).
Recently I renewed my medical marijuana card though I used it sparingly throughout the course of the year, to treat an insomnia and PTSD related conditions. 1 year later I am experiencing a noticeable improvement in the quality of my sleep and feel much less social anxiety than before. I am doing a number of other things for this using alternative therapies / herbs and supplements, so I am not able to attribute it all to cannabis. My personal understanding is that it can help to reestablish a homeostasis and or biorhythms from various imbalances caused by taking pharmaceuticals within a routine or controlled environment.
