I had been using drugs for some time. Right after I purchased new supply I was arrested and charged with possession with intent to sell. How can they do this when the police have no evidence that I ever sold any drugs to anyone?
If you were charged with possession with intent to sell drugs the police do not have to prove an actual sale; only your intent to sell the drugs. If you had just purchased the drugs you might have more in your possession than required for one or two uses. Also it might be packaged in several small packages which might indicate you intended to sell it to others. It might be important where you were arrested: at home or in the vicinity of a drug market. Many times these charges are highly speculative. However, if you are successful in rebutting the charge of possession with intent to sell, the police would still have the conviction for simple possession.
