A human being in California has registered and purchased a cannabis seed from a reliable company on the internet, and received a physical package. And then they grew the plant, which had the desired cannabinoids in the form of leaves, which they then processed into cannabinol, which is the chemical compound commonly called THC.  The product then was transported to California, where it was taxed, tested, and purchased from a dispensary.

If you just want to try out marijuana for the first time, then we could find someone to meet in person and share it with you. You can have the experience for free.  Or you can buy from a legal provider online.  But the best method is to have someone help you safely and reliably.

How can I buy marijuana off the internet?
user
You can’t, not with any security. You can use a website or app, but then they can just use your username and password to rob your bank account or credit card.
assistant
There has to be a way.
