The risk/reward equation for recreational cannabis use is either at the top of the list compared to other recreational drugs, or near the top, for most people.
For people with chronic pain, it may be near the top of the list compared to over the counter and/or prescription painkillers. If grandma is in chronic pain and is losing weight, get her some thc/cbd 1:1 gummies.
Ingested (versus inhaled) at the right dose, it's a powerful psychedelic that can be used to profoundly alter your conception of self, change unwanted habits/reactions, and better connect/empathize with others. Psylocibin mushrooms and a few others are probably a better option for this, but THC is more accessible.
Drugs are tools. Some tools serve almost no constructive purpose, like recreational meth. But many have utility if applied thoughtfully. Black and white thinking based on what you "learned" in a government school will not serve you well here, much less anywhere else.
If you're type A and need to chill the fuck out, cannabis is a wonderful solution. If you are fighting with your spouse and need to empathize better to have a constructive conversation, try it. If your sleep is shit, try an Indica strain before bed. If you're doing the program and "can't eat enough," etc.
However, if you have poor self control and have issues accomplishing what you want to in life, I wouldn't recommend it.
Don't want to inhale smoke? Eat it. Start at 2.5mg for at least three attempts if you weigh under 150lbs. Start at 5mg if you're above 150. Carefully increase your dose, 2.5mg at a time, from there. Take too much and you'll seriously regret it.
Worried about your testosterone levels? Why aren't you already on TRT?
There's a downside to everything. If you're getting fat from the munchies, noticing memory issues, or are medicating constantly to escape your existence, you may be skewing the risk/reward equation unfavorably.
