What recreational drug could a person inject right before driving?

I know it’s a weird question. I’m writing a fictional story and have someone injecting something in their car. A friend pointed out that no one would get in their car, inject something and then drive. I’m sure that might be true for heroin, but is there another recreational drug someone might inject for ‘fun’ and be able to drive (albeit under the influence) afterward? I mean not totally floating and with eyes rolling back in head like I’ve seen in the movies when people inject stuff. Thanks.
