ive smoked alot of weed in the past 5 years, but not smoking anymore due to some problems with the law, but i have never had panic or anxiety attacks while im all high.
Everything is good in moderation...too much weed equals retard, too much test equals king of the world.
Best way to kill anxiety is to get some phenibut powder- bulknutrition.com's got it, take about 740mg per day and I gauruntee you will conquer the block.
