if you read the article it seems they are well prepared with this coming change with over 9000 trained to issue prescriptions, where did they spring from???, and they are ready to roll.(new role for medical dropout students)
Not much expense just change the signs to look more respectable, rename the shop a medical clinic and dress everyone in white coats, simple all over nothing will change its a lot of gobbley gook.
The other question is who will monitor the THC levels if 9000 trained prescription issuers are ready to roll that means 9000 shops will be ready to reopen and 3000 will have to wait for more trainees to pass the medical school .
(requirement, be able to write a prescription, take blood pressure, use stethoscope, and bingo you get your ganja)
