ok i emailed them and asked how do they make sure the person is an actual medical user and what the catch is.... this is the response i got
There is no catch... nothing needs to be bought. We do ask any medical
users to provide us with a copy of either their license to produce or
possess medical marijuana or a signed prescription from their doctor. As
long as we receive either of the above, we will ship seeds free of charge.
If you have any other questions, please feel free to contact us again.

Thank you,
