What? I have to hold it in my lungs until time stops making sense. Like if I inhale and the almost immediately exhale like I would with weed I'll get a slight buzz and crystallizing visuals but also a ton of smoke comes out and smells like shit. If I hold for 15-30 seconds or until the numbers I'm counting become incomprehensible I'll have a full trip and very little visible or smellable smoke comes out.
