Cut the bottle open and scrape it.
One wonders how 2 grams of crack ends up coated inside a 500ml plastic bottle.
sorry, but I meant I have smoked 2g using this bottle and it's the oil collected to the sides inside I'm talking about. Thanks for the replies folks. I'll cut it open and scrape the oil out someway using a blade maybe.
Yep, a razor blade is probably your best bet, a stiff index card might work too.
