If you are used to smoking regular, like me, 3 good hits off some chronic or hydro should get you real high. Although what people call chronic and hydro varies. Where I'm from Chronic is not a name of a strain, but and adjective used to describe premium grade stuff. Same for Hydro except this refers to the method of growth, premium stuff grown by hydroponic methods. Either way, it should waste you with very small amounts. May take longer to take effect but will be better and last longer, try 3 big hits, wait 30 minutes after that before you decide to smoke more or stop. Enjoy.
