to cut back from smoking 5 grams of syncans a day, i've been using 5g/2 days but also taking 200-400mg of DXM every other day
i'm not sure which would be considered worse in the severity/harm factor
Most likely the Syncan, DXM is at least researched and known to have mild harmful effects, but is still intended for human consumption. Whatever is in the syncan stuff is meant to 1) sell and 2) Get you fucked up for a short amount of time with no regard to how safe it is. I saw an interview once where they asked one of the guys who helped make one of the JWH chems before it was on dead plant matter, "what do you think about the people smoking it now", the guys replied, "are you fucking insane?"
