The direct answer
Yes. Dispensaries can send text messages to customers when they use appropriate consent, identify the sender, provide a reliable way to opt out, use registered and supported messaging routes, apply required age and audience controls, and follow the cannabis advertising rules that apply to the store and customer.
The rules depend on the message type, jurisdiction, consent obtained, messaging route, recipient, store, and content of the campaign. A promotional offer, order-ready notification, customer-service reply, loyalty message, and review request should not automatically be treated the same.
Promotional texts
Require clear permission appropriate to the marketing program
Order texts
Should remain connected to the transaction unless marketing consent exists
Messaging route
Must support the business and declared messaging use case
Customer control
Opt-outs must be recognized and applied across the program
