I've wasted so much trees! ='(

So I hate the smell of bong water, makes me wanna hurl. So awhile ago I put mouthwash in my homemade bottle bong and it stopped smelling, gave the smoke a nice minty freshness. I did notice I wasn't getting baked off of it anymore though. I figured it was my tolerance or something. I just cleaned it out, clean water and mouthwash, packed it then thought, let me make sure this isn't harmful. Well I guess alcohol breaks down the THC, so shit, I have wasted some weed. To give you an idea I buy around 6g a week
