What's a common occurrence in your hobby that you think shouldn't be?
For me it's driving while under the influence. If you couldn't tell, I like me some ganja. However I have long since held the belief that it is utterly insane to drive while under the influence of most substances, with maybe nicotine and caffeine being the exception. All too often I see other stoners smoking and driving, which I simply can't fathom. I've only operated a vehicle once under the influence and it was just to move a U-Haul around the block to a different parking spot, which was such a scary experience while high that I refuse to even consider getting behind the wheel again while high.
A hobby is considered to be a regular activity that is done for enjoyment ... Participation in hobbies encourages acquiring substantial skills and knowledge in that area.
Just because alcoholics attempt to justify the fact that they want to get drunk whenever they want to by "tasting" wine doesn't make it a hobby. It just makes it sad.
Sorry that OPs hobby doesn't fit your blinkered view of what a hobby is. Amazingly, you are just one person in almost 8 billion, and it's completely plausible that you might just be wrong here.
Wind your neck in and go smoke a joint. You clearly need one.
I am a psychonaut. I am someone who explores myself and the world around me through the use of perception altering drugs in order to give me perspectives I wouldn't be able to achieve otherwise. Cannabis is one of those drugs and has genuinely helped me in treating my depression and anxiety, as well as connecting with other people. Additionally, it has given me a lot of cannabis related skills and knowledge which helps a lot when you live in a legal city where the weed is often stronger than a lot of people can handle. Through the use of weed I have helped many friends and myself discover things about themselves and their situations that would be difficult otherwise. I've made great friends and lost important relationships because of drugs, but yes it is a hobby even if you do not consider it one.
I offer you brownies and ask you to tell me what a substantial skill is and you insult me? Why? Reads like you might be bad company.
…
I thought 'smoking weed' to be an obvious pars pro toto for 'consuming marihuana' so if we want to return to the original topic: smoking weed for a long time gives you substantial knowledge about smoking weed. When to do it, what to mix, how to roll a blunt, operate a bong or vaporiser, just how to roll a spliff in your hand on a windy beach or how to decarboxylate your shot properly.
Now are these ubiquitously useful skill? Not really. Are they very useful in terms of getting very high? Absolutely.
I find the original question to be kind of silly. Of course smoking weed can be a hobby. If whisky is a hobby, weed is, too.
