okay first off, i know inhaling weed or anything else is dangerouswhy i dont do itbut my friend doeshe made a pipe out of like copper fittings for plumbing purposes and such (looks pretty neat) and then used like alluminum or tin bowl for the weed, i dont think this is safe because wont the burning of the copper and tin/alluminum is dangerous? could it kill him? is it safe? i asked him not to use it until i found out.
I know a lot of my friends in high school made one hitters with foiland they're not deadI don't know how safe/unsafe it wasI would say google itIt's pretty common so you should find lots of info :)
