For quite a few years I used to indulge moderately heavily in cannabis and now they tell me it's medicinal for every condition under the sun.
Was I self-medicating prophylactically ?
The claims for cannabis as a Panacea are misleading, misguided, and potentially dangerous.
In my opinion, I think a lot of the perceived benefits as well as the reported ones are based in the fact that we humans have something called the endocannabinoid system, which seems to be geared to be some kind of interface between the material (physiological) functions of the body and the more esoteric (feelings, thoughts, reactions, experiences) functions of the mind (or mind/body complex).
Cannabis seems to meet that bit where our hormonal and nervous reactions (fluids and electricity) responds to exterior stimuli and emotional responses, and translate those into stuff that lands in the body (feelings, reactions etc).
So much illness has an invisible component (stress, grief, fear, loneliness, anger, shock etc) and the place and the mechanics of how that becomes symptomatic is mysterious .
I reckon cannabis helps organise, elucidate, and harmonise that interface so it's less dysfunctional, leading to relief of the physical impact.
Works better /worse for some people, for some conditions, some circumstances etc.
In my opinion.
