Bear with me, but the cost vs profit ratio makes lacing a ganja spliff with anything "white" as a bad business move. As Capt D mentioned, the drivers in our Transport section are vetted. No one in our Transport section would risk that nonsense. An inquiry, trial and jail time is generally not good in the transportation business.
But it is common sense to never buy a pre-rolled spliff anywhere by some total stranger. Sometimes ignorance is not bliss.
Every driver in our Transport section has already been vetted and would never risk their license for less than the price of a return airport trip.
Common sense dictates not everyone is your friend, but we know all the drivers here personally and you can rest assured that they will steer you in the right direction.
