You would have to make an argument, again, to support the idea that the potion is faking love instead of simulating real love.
Substance abuse/alcohol abuse has debilitating effects on your life and health. There are no established negative side effects to the love potion being pointed out. You're just suggesting that there are and equating the two.
"There is also a difference between love instigated through normal biological means and artificial means."
If the potion serves only to stimulate the typical biological responses to how you feel towards someone, then wherein lies the difference?
Even without the person being literally steps away from death from substance abuse, it is still highly discouraged, why do you think that is?
Because it negatively impacts one's life, both their own body, mind, and their own social life, and often without the person's own knowing because they're stuck in an altered state of mind and a lot of times being unable to perceive and think over things properly as they would when without the influence of external drug intakes that directly affects their decision making.
So how are you going to tell me that it is QoL improvement?
.....
Speaking of negative impacts on one's body, are you going to assume that drugs that invade your brain and its function is not going to have any side effect or even permanent damage if used for prolonged periods of time?
Even Ritalin which is illegally taken by some people to boost their mental focus (as it's made for people suffering from attention deficiency related issues; it's illegal taken by your typical joes primarily as a form of cheating in fields that require strong mental focus, such as in exams) and viewed on that basis as being a 'superhuman drug', still has a bunch of both short term and long term negative side effects because it directly interferes with the chemistry in the brain. So on what basis do you think this love potion is going to be absolutely safe even though it touches the brain the exact same way as any other chemicals that does the same stuff, just in different areas?
I'll also have you know, brain is not like the rest of the body, it is both incredibly delicate as well as being not very robust and neither is it particularly good at regenerating itself. The brain does not have anywhere as high of a substance tolerance as the rest of the body would, nor is it anywhere comparable to being tolerant to injuries; unlike the body that can get poisoned and live to see the next day because it has a somewhat high toxicity resistance and mechanisms evolved to get rid off the said toxicity, the brain is not so tough and as little as a few neurons being damaged in the brain could potentially lead to drastic consequences such as memory loss or even function impairment, and they generate at an incredibly slow rate too which is why many of the brain injuries are compared to being permanent because the injuries will not be healed in the person's lifetime. WHICH IS WHY, unless absolutely necessary, drugs are designed to NOT go into the brain, as anything that goes in there risks unwanted and potentially permanent negative results; even for drugs that do go into the brain, various assessing points of WHAT IT IS and HOW MUCH USED and WHAT DOES IT DO and others are also strictly looked at. And this is also why, unless the love drug is used as a form of treatment, which in that case it will be heavily regulated and will only be used on the minimum amount required to solve any related situation, this drug is generally unwanted.
The "If the potion serves only to stimulate the typical biological responses to how you feel towards someone, then wherein lies the difference" is not rationally sound, because we can all say that heroin is just stimulating the typical biological response to make you feel happy, and ofc it doesn't work like that. IMPLICATION is incredibly important, as shown above. It's easy to conclude that this drug may only truly exist in medical field (and like most drugs that have to do with brain, it will also be locked behind tight supervision, like the mentioned Ritalin is), or at least if commercially available it will only exists as a pointless and very ineffective over the counter drug that either as a negligible dose or induces similar results indirectly via things like making your heart beat slightly faster or something, and then go out of market quickly because of the negligible effect in spite of its advertised name and implied effects; and heavy dosing is no different to any other substance abuse, and thus discouraged and not allowed.
.....
And all of this I have not even touched the social implication of using such a drug, if present for sale in a noticeable potency. As mentioned, it opens doors to all kind of crimes related to abduction and rape and other similar stuff, as well as a bunch of issue in trying to trace the responsibilities relating to the topic.
As such, might as well never okay the damn drug for mass commercial use, no need to create your own troubles.
.....
EDIT: Also, the main focal point is not whether or not the love is real, at least not a major point (sure, "lying to yourself" and "living a lie" or "forcibly and noticeable altered state of mind" is enough to question the nature of the product, but even that takes a backseat on an overall scale). It's that a drug that is capable and potent enough to noticeably or even significantly influence one's decision making, should simply not be openly accessible, due to all of the other biological and social implications I've discussed.
