Yes. It’s replaced coffee and cigarettes for me. It instantly quiets all negative emotions I’m feeling (mostly boredom and frustration) so I can focus on the code. I’m lucky to live in a legal state.
I've found myself in a situation now where I am almost unable to code without being stoned. When I began smoking, I got over more than a decade's of insecurity over being a sysdadmin who couldn't "really code". Now it's sort of intertwined. Without being stoned, I just stare at my screen then switch to a news site after a few minutes, then repeat.
