it's a great fallacy to presume that he is addicted to cocaine. if you happened upon somebody carrying a six-pack of beer you would not presume that they are addicted to alcohol.
Because alcohol and cocaine are obviously equally addictive 
cocaine is slightly more habit-forming than alcohol, yes, if our sole metric is the percentage of people who try the substance who in turn become dependent on it. of course nicotine and caffeine leave both in the dust in this regard.
Sample bias, of course. Cocaine is only harmful if there's already existing problems
