Considering that mushrooms do not have yet any legally recognized medical uses, they are still classified as a Schedule I controlled substance, making any kind of possession unlawful. As a result, there are various levels of legal and financial repercussions for the use, possession, distribution, sale, and trafficking of magic mushrooms. Shrooms can only be found on the black market, purchased from someone who bought them there, or grown using spores (a wide variety of psilocybe spores are legal to purchase, as long are they are not germinated yet. They can only be used legally for laboratory research).
Despite the fact that possessing mushrooms is against the law, the quantity in a person’s possession, when they are caught, will greatly influence the kind and severity of state-level criminal charges they will be subject to. Also, infractions under federal law for simple possession of mushrooms depend not just on how many mushrooms a person has, but also on their criminal record.
So, if you intend to travel with mushrooms, do not bring a lot of them, otherwise you risk being suspected of having sales goals. Additionally, since they are much more discrete, food and tea infused products are better choices for travelers than mushrooms.
You must also be careful and strategic about packing the shrooms in the luggage. When traveling by air, place them in your carry-on bag, and when driving, secure them in the trunk of your vehicle.
