I have increased doses to 7.5ml(3 pills) I am able to function fine while on the job--- yet find myself a bit mellowed out!!!!!!!!!!! This is great!!!! and legal!!!!!!!!! It does not compare to smoking marijuana thats for sure, but it is good to take a few pills in the morning and then go to work--- with out having to worry about getting fired. I am going to have my doctor change my perscription to the 5ml:stoned::stoned:
