Not even the same argument. Coffee doesn’t make you fall asleep and get stupid. THC and pot does. Only a stoner would even think to make that comparison.
No one is making the arguement that you should actually fly planes when you are high.
As a frequent THC enjoyer, I do understand that the same common sense rules we used to have about alcohol mostly work with THC as well. Don’t get high and fly planes, drive buses, do brain surgery, etc. But if it’s the weekend and you have nothing going on and want to smoke a joint instead of drinking than go for it. It’s probably a little bit healthier than booze and it serves the same purpose.
