I think pot has gotten a lot more potent since I started smoking thirty some years ago. But I do take into consideration that I bought ten dollar lids of homegrown.
Living in another area for many years, I could only find dirtweed. I'm sure the good smoke was there somewhere, but for 13 years, I never found it.
Moving here to the SF area and having my recommendation, I have NEVER smoked buds more potent than I do now. The term "one hitter" definately applies.
And I love it!!!
