“The problem with many FDA approved medicines is that we as a species evolved without them”
Scientists have determined how various processes work and how they go wrong. Medications like Xanax are an attempt to better modulate those processes. The reason we have side effects is that once nature finds a process that works, it uses it over and over to do different functions. So, a misfiring nerve in the cortex might be positively effected by a drug but other processes in the body use that very same process to accomplish something else. On top of that, although humans are largely the same on the macro scale, at the smaller scales some of us have more nerves in one area than in another area, thus side effects can be deadly to the percentages of those people who are assembled slightly differently.
There is no more addictive ‘medicine’ than Xanax.
All the benzodiazepines are dangerous.
