HARRISBURG (AP) – The PA Supreme Court says the smell of marijuana can be a factor police use to justify a search without a warrant, but can’t be the sole basis for it. The state’s top court ruled that a state police search of a vehicle in Allentown three years ago was conducted only because the troopers smelled marijuana. A trial court had ruled the search unconstitutional and said the evidence it produced was not able to be used in court, and dismissed the charge of possession of a small amount of marijuana. The Supreme Court majority reinstated the order suppressing the evidence.
