Well I don't think doing cystal meth will do you a lot of good, but I have never heard it making the injection not work. If anything it might screw up your fertility...
Wow.
Try using a condom! We have enough drug-addict welfare moms who treat their kids like crap. Dont be another one.
Stop using meth. If you don't it will ultimately raise your blood -pressure, destroy your kidneys and your liver. By that time none of it will matter.
i agree with laura d... DONT REPRODUCE!!! clean yourself up and have some self respect!
why in the world are u using crystal meth? and if thats so important to you, i am surprised you are even remotely concerned about anything else. that is ridiculous. if you are that concerned with meth, please do everything you can to avoid reproducing for gods sake.
