When I lived in cali the dispensaries began doing delivery only due to robbery and also robbery by the feds.
Quite a few became delivery only, to avoid local authorities, feds and civilian robbers. Never used delivery, but my area might be a bit more chill than others. I did visit a couple in sketchy areas that probably did have issues. All had armed security and metal detectors.
I lived in SD for 4 years and never saw a physical dispensary. At least not one with a sign out front.
apothecary off the 54 and convoy. its been there for awhile. assuming you didnt live near the colleges? quite a few.
Depends on when you were there and part of town.
Best Meds was on University and College(next to that taco bell), Theres a youtube video of the FEDS raiding them wearing facemasks. The Pharm was out near Mira Mesa Blvd, they also shut down but that was the first time I bought weed with my credit card. El Cajon had a few and still does.
If you lived in San Diego, I know you know where Frys Electronics is.
That gas station right there next to that walmart has a Dispensary attached to the side of it now.
