Estrogen increased by weed is a myth that was disproven over a decade ago. If you don't believe me, check errovid.
I suggest you smoke hydro or kind bud(the good shit that costs $100+ a 1/4 oz) out of a water bong. That way you don't need to smoke as much and it's easier on the lungs. I wouldn't smoke regs/mexi-brick shit if it was given to me. I can get a fat oz of that stuff for $70. Fortunately the kind 420 is just a phone call away for me. Purple Kush and Blueberry are my fave. Northern lights, Dump Truck, and Popcorn are good too. I feel sorry for you guys that don't have access to Amsterdam quality bud-you're truly missing out. If weeds slows you down, try popping about 50 mgs ephedrine and some espresso, vivarin, or red bull.
