Benzos are ok if you have self control/discipline to not take MASSIVE amounts everyday or even taking small amounts daily can lead to physical addiction. That is the main reason people say to stay away, because a majority of people love benzos and end up taking them everyday shooting up their tolerance real quick then they take higher and higher doses more frequently and than a year blows by doing this, they try to go a day without and WHAM ! withdrawals...
So if you go with benzos... be disciplined about it, physical addiction to benzos is super dangerous. But other routes for anti-anxiety are: Gabapentin, Pregabalin. SSRIs: Celexa, Lexapro.

it's basically the marijuana wikipedia. You can research which strains/kinds of marijuana are good for anxiety suppression and it's fun too cause they show beautiful pictures and have a cool layout for flavors, medical, beneficial and negative effects so you can get a complete description of every strain to find the one that would be right for you, then it helps you find a dispensery that has that strain near you. It's one of my favorite sites ;p
