First off I know more about it than I will make you aware of. Second, not every strain of M is going to be able to give you the best iron sessions. Third, I would say people that get stoned then go to the gym are a minority. Fourth, about people, everyone handles their substances differently. I have come across many folks who smoke M everyday and they are complete turds. They are in their own world, have nothing decent to contribute to society, undesirable, and M use is a stepping stone to other vices and more serious substance abuse and criminal activity. For many, M causes amotivational syndrome. Look up amotivational syndrome. And obviously, strains with higher THC content make these traits and attributes more pronounced in people. The withdrawl from M, especially cold turkey can and does cause a plethora of psychological problems long term. There are many people that keep this country safe and society civilized that do not use M. Quite frankly in a sense, heavy M use in most younger people alters and weakens development. So those are a few things not good about it. Now to come down to your level, I will say M is definitely the lesser of two evils a hundred fold when compared to stimulants like cocaine, amphetamines, synthetic drugs like bath salts, other drugs like opiates, alcohol. If you can afford, and i'm not just talking because of a financial cushion, than do what you want. Just understand there's repercussions for anything we put in our bodies. Some substances of which that are not as universal to the masses.
