I've always found it easy to look at this situation in this way. Maybe you will find the same.
If we take all known stimulants and we put them on a spectrum or in some kind of hierarchy, in my mind, we end up with something like this:
Caffeine
-
(Pseudo)ephedrine
-
Propylhexedrine (Benzedrex); the inhalers made for allergies/congestion, the cotton inside of which contains the drug, which is a very mild CNS stimulant
-
Phentermine (Adipex); this isn't a commonly used drug anymore. It's a CNS stimulant used specifically in weight management/obesity
-
(Dex)methylphenidate (Ritalin; Focalin)
-
(Dextro)amphetamine, including mixed salts i.e. "Adderall"
-
Methamphetamine; still a prescription drug, yes, though 99.999% of Methamphetamine use is of the illicit variety.
In my opinion, all of these drugs have the ability to get us feelin "high", despite the label of Caffeine and Pseudoephedrine as "Peripheral Nervous System" stimulants. For a totally naive person, a high dose of Caffeine probably feels like one of us taking an Amphetamine pill. The thing is, I think most people who are self-identified "Caffeine Users', not just a morning cup of coffee type people, use too much Caffeine. Like any drug, they remember the benefits Caffeine used to provide them, this leads them to drink more Caffeine even though they've already crossed the cost-benefit threshold of the drug a long time ago.
For the sake of explanation, I group Ephedrine products as basically right next to Caffeine in terms of intensity, so i'm not gonna devote a ton of writing to it specifically.
Then we have the more common CNS stimulants of the Amphetamine and/or Cathinone classes. These are potent, yes, but they're just like Caffeine at the end of the day. A person can become tolerant to Amphetamine in nearly the exact same way, where the end result has them taking more Amphetamine despite crossing the aforementioned cost-benefit threshold of the drug.
The difference with using too much of these more-potent CNS stimulants is radically different to weak stimulants. You're seriously messing with brain chemistry when you reach a point where Amphetamines no longer work. The symptoms of this sort of thing include the usual jitters and what not, though you start to see symptoms of lost sanity coming into the picture as the person's reality becomes distorted by the Amphetamines. The thing is, with Caffeine, you can easily go from naive to totally tolerant in a couple of weeks. A person's trajectory with something like Amphetamine is going to be months of dosage increases before the drug becomes worthless and the person runs out of steam.
Methamphetamine is at the far end of the spectrum. It's one of the most potent stimulants known to man. Frankly, I don't know that man could easily tolerate a more potent stimulant even if it came into vogue, as Methamphetamine seems to turn out people's bodies and minds at a pretty crazy rate already.
The spectrum I mention is meant to illustrate that all of these stimulants can have a similar function. At the end of the day, I feel they all share similar qualities, with tolerance being a major factor in the perceived potency of each one.
