All versions of the pill can have negative and permanent side effects. If you ever get a chance, read the patient insert for any brand of BCP. One of the side effects listed is blood clots leading to death or disability. Pretty permanent.

That’s not a common side effect but neither is it restricted to older versions of the pill.
If you watch TV much, you may have noticed one of the newest brands of BCPs is running “correction” ads. They say something like “the FDA told us to correct some misinformation from previous ads”. The “misinformation” was not clearly informing about the side effects. If you watch TV late at night

, you may also see the lawyer ads seeking class action members to sue the same company as makes the aforementioned pills over some very nasty side effects.
BTW, one of the
most common side effects of BCP is loss of libido. Now, shouldn’t that be avoided?
That being said, whether or not BCPs have side effects or are safe doesn’t change the morality of their use. The only thing that matters is if they are being used to treat a condition itself (moral) or used to prevent pregnancy (not).
