Since August 1969...daily. Plus I used to be a die-hard old-schooler & thought our weed in the 1970s [Michoacan, Oaxacan, Acapulco Gold, Panama Red, Thai-Sticks] & the weed in the 1980s [mainly Colombian/Santa Marta Red] was the best weed.
Not anymore!! What my pals grow is amazing. Names that sound more like LSD than weed. I'm currently tokin some AK-47 x Freezeland. Also have some Genius x OG with a Lemony Pheno(?), White Widow x Blueberry, BR_1947, Kali Spice. I take 2-3 good bonghits & I'm wastoid for 3-4 hrs.
The weed we toked 35-40 yrs ago, we could smoke all day. This new stuff that these 'gourmet growers' are producing nowadays, there is no way in hell I could smoke all day. I'd be a vegetable. I'm totally convinced that what is grown in this day & age is way more potent than what we got 40 yrs ago.
