Right at the outset you must know that not all states allow buying or selling of weeds in any form. Therefore, right at the very beginning you must know whether the state that you live in will entertain and approve your purchasing of weeds from any store, online or offline. Moreover, you must know that getting weed edibles shipped by UPS or FED-EX to you is also a federal violation of shipping controlled substances. Any use of freight carrier is regulated federally and if you are unawarefor any wildreason, other states that legalized it are doing so against the Congressional Law.
Pot is illegal
Therefore, to make it short, sweet and simple, pot is still illegal to the Feds. That means such online orders cannot be placed because you and the shipper will be charged and exposed to federal felony for transporting such substances using a federally regulated carrier. These carriers usually inspect each package before shipped to find whether or not there is anything illegal in it. In case it is found to carry controlled substances, these carriers need to contact the relevant authorities immediately according to federal law. That means, if you want to buy edibles online, the safest way is to visit a brick and mortar business.
The eligibility aspect
However, buying of weed edibles online is permissible to those people who are eligible for it. The requirements for eligibility include residing in a state where smoking marijuana is legal. You are not supposed to leave such a state with them or else face felony conviction once again and may be a long prison sentence as well. Apart from that you will need to over the age of 21 years. You must furnish an authentic ID proof that is verifiable though you may not need a medical ID when you visit such a store to buy weed.
