Dealer Across The Street??

I'm not a 100% sure but the Southern California in me is screaming: "They're Drug Dealers!!!"

The house across the street is inhabited by a black family.(Yes i said black, you're not African American unless you are from Africa and your ass moved here. If you were born here you American, Get over it!) They seem like typical non-social neighbors who go about their business and dont ever cause any drama or BS that I can hear or that I notice. But....

Constant Visitors-When i go outside to smoke a cigarette, drink my tea or whatever, it doesn't seem normal for cars to continuously stop by for 10 min or less. 
Its never the same cars either, a few here and there are repeat visitors but usually its just random vehicle after random vehicle.

They never sleep- it does not matter what time i go outside 1 pm or 1 am their lights are always on and the vehicles continue to visit.

Walk-Ins- There are random moments where there are at least 6 cars parked outside and ill see someone leave. They walk outside passed every car and just walk. Where the hell are they going? 

Drive By's- Yesterday and Sunday i watched as a car pulled up, a thick woman in scrubs walked out to the car they did a hand off kinda trade and then the car left and the woman went inside.

All suspicious if you ask me. It might all be circumstantial but like I said before the Southern California in me was just screaming that they are dealers.

What does this mean?
It means that when they get caught i will go outside and smoke my cigarette and drink my drink in my front row seat out on the porch.
