I have been smoking marijuana for 8 years straight everyday, whatare some of the worst thing that could happen from pot smoking?

See below: Like cigarettes- cancer, stroke, heart disease , lung disease not to mention cognitive impairment, low testosterone, psychiatric problems, weight gain and lack of control of other appetites. But otherwise its harmless.

Weed side effects: "smoked marijuana damages the brain, heart, lungs, and immune system. It impairs learning and interferes with memory, perception, and judgment. Smoked marijuana contains cancer-causing compounds and has been implicated in a high percentage of automobile crashes and workplace accidents.".
