Comparing the addictive properties of a crack cocaine high to asphyxiation with refrigerants is kind of like comparing apples to turds.
crack cocaine unlike most substances can literally get you hooked with one hit. Do you think the people you see begging for change or cashing in aluminum cans for crack money, had any different intentions when trying crack than you do.
Now is it a guarantee that you'll get hooked? no absolutely not, but the only way to find out is to try it. Look in the "rate a drug on a scale from 1-10 thread" crack isnt even that favored among most people who try it. Its far to addictive and doesnt last long. Way better things to try and actually enjoy.
