Hi there! The current taxes for cannabis are a 15% excise tax as well as sales tax. Every one (including medical patients) are subject to the excise tax. "In order for the exemption from sales and use tax to apply, the customer must provide you with a valid Medical Marijuana Identification Card (MMIC) issued by the California Department of Public Health and a valid government issued identification card (ID). A physician's note is not sufficient to support the exemption from sales tax." You can read more here: http://www.cdtfa.ca.gov/industry/cannabis.htm#Retailers
If you have a recommendation through HelloMD, you can use that to apply for your MMIC. You'll need to apply with your county and then they will fax us documents to verify your recommendation. You can have your county fax us at: (415) 329-1407. To find out where to apply in your county, please visit this page: https://www.cdph.ca.gov/Programs/CHSI/Pages/County-Program-and-Hours.aspx
Hope that helps!
