Does smoking weed slow height growth?

Not known; unlikely. It is not known/studied about, but i don't believe marijuana use causes any growth problem--possible if woman who is pregnant and smokes her child may be small. But, it causes many other problems, often psychiatric/mental symptoms and some physical symptoms such as dizziness, incoordination, diahrea, sweating etc...The worse is trouble with the law! still illegal to use/carry/sell. So, be good!
