Lean 

To be high/ under the influence of cannabis and only cannabis. Consists of mainly a body high (a high that affects the body, e.g. Not being able to walk straight would be a body high however not being able to think straight would be a mind high). It derives from ones legs not being able to withstand the weight of a humans body and so they must lean on something to stay upright.
