I'm totally with you on that, Rain. Most store-bought pot doesn't do anything for me, either.
However, legalization also means I won't get hassled for growing a few plants on my back deck. Also, once legalized, the market naturally responds to consumer demand, and most adults over 30 are demanding lower THC levels and/or high CBD levels for medicinal applications. Consequently, growers are now breeding strains for other goals beyond knocking you on your butt, such as pain relief and epilepsy mitigation.
Free-market capitalism. It works if we just let it.
