Okay so since i started doing track i have had to stop smoking out of my lovely bong. I went to the local head shop bc i was interested in vaporizers. and they have two different ones im interested in. One is about the size of a pen and you use a lighter to work it( it basically looks like a pipe). The other is a typical brown wooden box one that pluggs into a wall outlet. Now i dont want to mess up my lungs at all for running so which one would yall reccomend? any expierance with either type. The first is 50$ the other 90$.
