What is it?  What are the symptoms?

yes but don't order it online. I did and it was  fake i had my doctor the have it checked and there were no signs of thc or cbd so i suggest you get it from a dispencery. 

Yes it does for some..trial and error

Do you or anyone has this FTD? And cannabis, as in weed? Personally I stay away from marijuana because I'm not that body type
