Note that I didn't compare social media to heroin, I've just made a simile of how something can be addictive just like heroin. I didn't say it was similarly addictive, and I didn't even compare their addictiveness, the simile was used to illustrate the point on a non-controversial example (which everyone knows is very addictive) And yes, you are entirely right - sugar and other things in that ice cream create an addiction - this is why you had ice cream yesterday even though you knew you shouldn't have had it!
