I just have to chime in, Weed cannot be laced with cocaine!!!!! That is why crack is made so you can smoke cocaine. If you put coke in a joint or a bowl the heat would make the cocaine evaporate before you could even inhale it. I'm not trying to sound like a know it all but at 29 years old I have done pretty much every drug you can think of. I'm not proud of this but that's life. If your grandson smoked weed laced with something chances are he knew, hard drugs are really expensive and as a former addict I can tell you I never got drugs for free or gave them away. Meaning, if you didn't have cash to throw in you weren't getting high. My guess is that your grandson is lying to you. He's probably been using hard drugs for awhile. After 3 years of abusing cocaine I was finally so fucked up that I decided to quit. Its not fun anymore when you just stare out your front window waiting for the cops to come(paranoia). Unfortunately I suffer from many side effects from my previous drug use and I hope you can help your grandson so he doesn't go down that path. I was lucky enough to have the help of my family when dealing with my addictions and it seems your grandson does too.
