Sorry it just bugged me to see a comment coming from someone that seemed to be completely ignoring what pot is supposed to be good for, one of the things it's used to treat! Everyone is obviously going to have different results, just like when taking anti-depressants or anti-anxiety drugs different ones work for different people.
I love the commercials for the anti-depressants with the warnings about side effects such as "may increase suicidal thoughts", etc. Kind of counter-intuitive that something that supposed to treat depression can actually make it worse in certain people. The ironing is delicious, as they say.
My favourite iatrogenic paradox is anti-anxiety tranquilizers, whose potential side-effects include; Rage, mania, loss of memory, depression, and impaired thinking.
There are other medications available, though all forms of anti-anxiety medication can cause some level of nervousness, sleeplessness and other serious physical discomforts.
And yes, they're addictive.
Even if you stop taking your medication, the anxiety will return soon after if you don't seek treatment in the interim.
Topping it all off, anxiety is a condition which is easily misdiagnosed.
