I've had pot like this in the 90's. Never had it again. Whilst doing g my apprenticeship we used to go to engineering college once a week. We were all smokers and took it in turns to bring buds in to smoke in our lunch break. A maye brought some in an was raving about the potency. We all sat in his car and passed the bong around 3 times. Big mistake. It was creeper weed, by the time we got out of the car, we were all fucked. I couldn't go back to class I was that bad. Sat on the toilet for 3 hours hiding. At 4 o'clock when college finished we all met up.my friends were green, teo of them had vomited in the training workshop. Honestly we were all stoned to the following afternoonI agree with that statement.
The only times it has happened is from home growers who have made selections over many years.
Never commercial crops.
One of them threw about 8 of us into some 30 minute long sort of telepathic giggle fit where nobody said anything and we kept looking at one another and seemingly knew what we were going to say then we would all burst back into laughing/crying incapable of catching our breath. I recall almost vomiting off the potency of the first toke and absolutely recoiling at the idea of a second. The smoke was practically liquid milk and made you sound like darth vader on exhale.
