It depends on what u meant by recover, the sad part is they take these drugs and it's like meth drugs, they ruin your mind and your life, it's just a downward spiral of deterioration of life till death.
They sometimes get drugged without realizing they got some bad stuff. And these people are the ones that can recover, but some do die.
Do a google search on flacca and you will see just what this drug does, the guy running into the car window and getting up and also hit by the car, is insane but there are ones like the guy down in Miami that the cops did shoot and kill because he was eating the face off another person.
Totally bad stuff.
