For starters props to you for growing for noble reasons :tiphat: You should never feel ashamed or like you wasted your time on something you enjoy doing; especially if that enjoyment brings prosperity and health benefits to others. There's an immense amount of time, knowledge, sweat, money, and personality that goes into growing cannabis, or anything for that matter.
That being said; sometimes we need to remind ourselves that our growing passions are not always the passions of smokers. I didn't even know the difference between CBD and THC until I started growing myself; so I could see the difference in smoke during different times of harvest. When I first starting smoking all those many years ago; I didn't associate smoking MJ with pain relief; I smoked it to get ripped, like the rest of my prepubescent friends at the time haha! Man, we smoked the crappiest herb you've ever seen. I don't even think it was weed half the time. We used to call it "the brownie mix," because you'd have compressed wafers or chips of brownish looking hardened, dried leaf material that sometimes smelled like gasoline at worst or if you were lucky, it smelled like fresh hay that's just been pissed on by a sheep. Seriously. You may not know that smell unless you grew up on a farm, but I digress.
Over time I came to know "kind buds", good cannabis; stuff grown more local instead of smuggled in someones gas tank. This is where a guy learns to appreciate the difference between crap quality and good quality. It wasn't until I met a grower that I learned the difference between "good quality" and "excellent quality." Getting a first hand look into just how much hard work and energy goes into growing quality herbs, seeing what the full potential of a plant can be if it's nurtured and loved and taken care of. Another milestone in the appreciation of cannabis. You couldn't have told me that in my teens. You could have; but some things take time to sink in. And even with that; unless you have access to these inner workings and knowledge; you could grow up to be a grown man (or woman) and still think it's all about "just getting ripped." So remember; not everyone has the exposure or
perspective as everyone else; we all walk a different timeline and see things differently and objectively. If your friends don't like your meds; it doesn't mean they are ass hats or guys selfishly "wanting to just get ripped," it means they are people that have different perspectives and life experiences than you. This is my personal motto (feel free to disagree but I've found it to be true 100% of the time,): "I can't force people to change their minds or attitudes, but I can change my own."
I'm not a medical cannabis user. At least; I don't think I am. I'm getting older. I have aches and pains. I have anxiety. I hurt for no reasons sometimes. I think it's called "being alive."

: Smoking helps alleviate a ton of symptoms that aggravate me; but on the other hand; I also just enjoy getting stoned sometimes. My Mrs. has fibromyalgia; so there's another side of the coin right there. Her reasons, though shared similarly with mine, are medically different. So I guess what I'm trying to say is that I don't think you should be disheartened by the opinions of your friends. At least they are being honest with you and not just telling you what you want to hear. And know that not everyone has the same mindset or opinions of what such a miraculous plant can be used for; and that diversity is a beautiful thing :hug:
