really you must be a bit shot mate i mean if u smoke thru filtered ciggies ya doin is filterin out most of the thc
if u wanna do it like this to be discreet then you can get the filter ciggies an jus take out the filter and replace it with a roach ive done this before, took a whole pack of 20 to a club cos they had a small bit of the filter sittin on top of the roach the bouncers dint notice then u can jus pop the top bit of filter off an smoke thru a raoch this is discreet and i jus like smokin a j
if ya get me
dont use a filter u will cut the thc content by half so really this way ur wastin half ur weed jus replace the filter with a raoch an if u go anywhere bait then put like half a cm of filter sittin on top of the roach then remove this when u spark it
its the best way
safe
