This reply is about smoking the meth. The most preffered way to make your own "meth pipe" ( I call it a pizzo) is to buy one of the little glass air fresheners ( trade name "Tribal Scents") from a liquor store, usually available at the front counter ($1.75 in socal). You will need access to a propane blow-torch ( $14.00). Empty the smelly liquid from the tube and remove the ball of felt. Clean the tube thoroughly with water and let it dry. Screw the plastic lid back on the glass tube. You have now completely sealed the tube and are ready to heat it. Set the blow torch on medium and very gradually heat the bottom ( glass only ) end of the tube, using the plastic cap as a handle, and be careful to keep the handle as far below and away from the flame as possible. Don't heat the end of the pizzo to rapidly or the glass will crack. Keep a constant turning motion so you get an even heat around the entire tube. Eventually, the trapped air in the tube will expand, while the heated portion of the glass will soften and swell to accomodate the air. When you hear it pop, you have a hole, therefore a pizzo.
The old method was to blow into the tube while heating it, but this caused lame looking and sometimes ineffective pizzos, and also brought my face dangerously close to the flame. WARNING!!! This method of dope-pipe making may cause an involuntary interest in the art of glass blowing. It did for me, but I was up for the next twelve hours with nothing else to do.
