Actually, I have to side with the original commenter on this. A great deal of today's public health issues in the first world stem directly or indirectly from people being unable to properly moderate use of a good thing. That's why I switched to decaf - I'd have to drink 10 times the amount of coffee I normally do to get an equivalent dose.
Ah yes, heroin and caffeine are equivalent, that's why we see all those caffeine addicts lining the streets of San Francisco looking for their next fix.
If you want to have an honest discussion, stop using these terrible analogies and bring actual scientific evidence.
This mentality of finding these shallow similarities and drawing these insane conclusions indicates that someone has very low intelligence.
This is your "deep" thought process
1. Caffeine is a drug
2. Heroin is also a drug
3. Caffeine can have negative effects on people when used in excess
4. Heroin can also have negative effects on people when used in excess!
There's a Starbucks in town whose unfortunate positioning has led to a great increase in wrecks (it's just past a hill, on a fairly busy road with speed limit of 40mph, and it doesn't have enough space for a large drive thru so cars are backed into the road).
Given your entire comment is one massive strawman argument I will ignore the rest of it.
