About 4 years ago Snoop Dogg's signature strain made it to CO. It wasn't around very long but it was 1 of the heaviest indicas I've had. Great stuff.
I don't doubt it at all. lol
Strongest weed I've ever had was a strain from Alaska called Mananooska Thunderfuck. I've only had it twice.
The first time was about 30 years or so ago when a friend who was in the Army was stationed up there and brought me some.
The last time was about 2 years ago when it showed up at a collective that I used to go to. I bought an 1/8th, then decided to go back the next day and get more and it was already gone.
I asked the budtender about it and she said "Dude, we were sold out of that stuff about 3 hours after you left yesterday". lol
