Earlier it was used a drug and due to its overuse many people had lost their lives. After that, the government put a ban on its use. However, in the recent times, many US states have lifted the ban, but there would be some strict rules and regulations for its use. If you want to take treatment at any of the weed dispensaries in Los Angeles, you need an MMJ card. This card will be issued to individuals who have got their physician's written permission.
When you have this card, then you can buy weed from any ethical pot shop. Please note that this card only provides you entry to the dispensary, however, your treatment will be started only after confirming your medical condition. For that some medical tests are performed and those medical tests will decide whether you need weed treatment or not. If it is found in the tests that your condition is quite serious and only marijuana can lessen your pain, then you will be allowed to take marijuana treatment.
