Snorting benzos is a waste. Smoking it is ludicrous. Benzos are best consumed orally. But watch your dose of you've really been snorting or smoking it, b/c the oral dose needed will be much lower, significantly so.
How did you inject it? In alcohol? Ouch. In PG/water - very thick. In water? definitely not.
Just consume orally and watch the dose. It's got a low threshold b/w remaining functional and winding up in jail, dead or simply passed out. It's not lethal, but people's actions while intoxicated certainly have been.
