Jahvisions,
I also feel bad about these teenagers using shrooms as a party drug, only to have fun. That doesn't work all the time and can have bad outcomes (which then leads to a ban in the Netherlands...)
I can only speak for myself and say that when I was abusing marihuana (I say abusing because that's what it was) on a daily basis it wasn't good for me. The plant itself forced me to stop - I became paranoid and couldn't enjoy smoking anymore. I'm glad that happened, it broke my addiction to weed.
Now I'm using mushrooms in high doses (6g+ dried) from time to time and my life is better than ever before. Weeks after a trip I am still more focussed, more confident and happier. The addiction potential is near to zero because every time I'm about to do a session I'm really anxious - the trip can be hard on you, nothing I would do every day, not even once a week.
I don't care about the low doses (the ones where the giggling teenagers were) because that doesn't work on me anymore. When I take 1 gram then I just feel a little awkward. More side-effects than a kick. Obviously I don't do that anymore, so there's no risk of a daily abuse.
Please don't say mj is the only good thing just because the rasta bible tells you to believe this. It's just another work of dogmatic beliefs.
Wrong usage of every drug can be bad, mj as well as mushrooms. You have to find the right usage for yourself.
