Substance abuse has a long and storied history closely linked with unlocking creative genius. But part of that history is that it always always comes with a price. In our biology, like with most things, there's no such thing as a free lunch.
The cost comes with abuse and that goes with anything, it could be beer, pringles and even food. I’ve consumed in moderation for 20 years and not on a daily basis and honestly I have nothing to regret and I doubt I ever will. There’s more damage done to my body from sitting down on a chair starring at a screen for 8 hours a day than the ocassional mj puff. Quite on the contrary, it has made me a lot more productive in moments when I was stuck and lifted the vail of the mundane conformity in thinking, enough to make me aware where I am too complacent and help me shake it off.
Downvoted? More like upvoted. THC is magic.
With one caveat, one may become too friendly to THC and then waste too much a time chasing good times. It harms one's best abilities if abused and it's quite easy to fall into that trap with the current trend of legalization. Not saying it shouldn't be legalized, no, I think it should but people should become aware of benefits and pitfalls.
