It's just a small glass container with an orange cap on it and it seemed weird cause it makes it hard to get the weed out. All I have ever seen before are baggies.
So someone sold you some weed in a jar? Is there a question about cannabis here that I'm missing?
You may want to try posting a general thread about what type of containers/baggies drugs are sold in, in Drug Culture.. This however isn't the right place for this type of question, closed..
