Whether your denial is plausible is a matter for a judge or jury. Your credibility might be stretched if, say, the drugs were worth a lot of money, you didn't report it when they turned up at your house, you had drugs in your house when the police searched it under a warrant, and you bought cryptocurrency which you can't account for a few days earlier. You might choose to take a plea rather than rolling the dice at that point.
