Working with a new patient with no experience of medical marijuana first requires some tutelage in the basics, the difference between indica and sativa, the two general types of marijuana plants. Sativa is more of a cerebral kind of high, during the day, you have to be at work you're in a little pain, but you can function and think. Indica is more of a stronger pain killer, more of a body high, it can put you to sleep. Typically you want to smoke sativa in the day and indica at night. Most strains mix sativa and indica in different proportions and then have varietal differences as well. The budtender has to find the right blend for the patient.
