Suppose Adam is an international student on a student visa in the UK. Suppose Adam is a recreational user of cannabis, hashish or similar, with no criminal history and no history (either on UK police record or in fact) of manufacturing or selling any controlled substance. Suppose Adam attempts to enter a venue while carrying a few grams of cannabis, hashish, or similar, and the bouncers confiscate the substance.
If the venue were to file a police report, how likely is Adam to be charged? Does Adam incur any additional risk because of his status as an international student?
I've read this answer on the general case.
