Comment: This op-ed letter sounds like Sean Hahn got into my stash, and got a little too high. Actually, smoking 1-3 cigarettes a day is healthy for you. It's smoking 1-3 packs a day that will cause health problems. Pertaining to Sean's laughable claim cancer and the like will go off the charts 20-30 years from now, we already have millions of heavy pot smokers for over 50 years, and his claim has not remotely come to fruition. As for being unhealthy for you...before I smoked pot my knees swelled so badly I couldn't walk. Pot gave me back somewhat of a normal life, and empowered me to get back to work. But why let facts get in the way of ignorance.
