Paracetamol disrupts early embryogenesis by cell cycle inhibition

Anyway, I understand arguments for avoiding drugs, medicines and chemicals altogether. Clearly, everything is more complex than it seems and side effects can never be fully known or understood; especially on a case-by-base basis given that everyone's DNA is different and responds differently to chemicals. I only take Paracetamol if I have a migraine with visual aura which is quite rare. I don't take it for standard headaches.

So if you're going to off yourself you'd have to stock pile or roam around shops picking up.

There is a not insignificant number of suicides where people just say fck it I'll just kill myself but they don't want to go out to any real bother to do it i.e. they don't pre-plan it it's just spur of the moment. A bottle of kill yo self pills is pretty easy. Cupboard, swallow, drink down some water, die. But having to go out and buy a bunch over a few days or like drive around in your car just buying as many as you can. Like you'd have to look it up to check you're going to buy enough.

Back when that law came in when they didn't reduce the total amount you could buy at one time so if you went in and bought like 10 packs at the supermarket then the person at the till would be like ok this person's going to kill themselves so again that would require a bit of balls from the would be kill yo selfer.

I think you can buy a bottle of like 100 x 500mg for like $20 in the USA. That's like over 2 weeks swigging at the max amount. Like you don't need that many, 3-4 days is enough shouldn't be taking that much of the stuff.

Never met a non autistic child who would spit or drool out calpol. I'd take the stuff myself as an adult it tastes brilliant.

> Total culture shock for me, as in Europe the default for children is rectal ingestion (which is probably a culture shock as well for Americans)

Huh are you talking about new born babies or something? I've been to a few different EU countries and you can buy liquid stuff for kids in the chemists. (Spain, france, germany, italy) source me as a child getting the stuff when I was sick abroad and the local doc sold my parents basically some off brand calpol.

More broadly speaking, anything that is claimed to be "hereditary" (which for ADHD the scientific consensus is that it is not exclusively but estimated at around 70%) could also be early nuture and prenatal environment. The way genetic inheritance is researched (identical twins vs. fraternal twins) cannot account for this. [2]

[1] e.g.

"ADHD has been clearly linked with numerous environmental risk factors, particularly around the prenatal and perinatal period. Some of the most robust risk factors identified are maternal prenatal health conditions and psychological distress (e.g. hypertension, obesity, pre-eclampsia, immune activation), in utero exposure to poor diet (with critical factors still being determined), teratogenic effects of certain medications (e.g. acetaminophen) and environmental exposures (e.g. lead), as well as neonatal factors such as prematurity and low birth weight [27]. Other extreme exposures in the postnatal environment (such as extreme infant emotional neglect) have also been associated with an ADHD syndrome [28, 29]."

"The convincing evidence for genes as risk factors for ADHD does not exclude the environment as a source of etiology. The fact that twin estimates of heritability are less than 100% asserts quite strongly that environmental factors must be involved. ADHD’s heritability is high, and that estimate encompasses gene by environment interaction. Thus, it is possible that such interactions will account for much of ADHD’s etiology. Environmental risk factors likely work through epigenetic mechanisms, which have barely been studied in ADHD [148]. The importance of the environment can also be seen in the fact that, as for other complex genetic disorders, much of ADHD’s heritability is explained by SNPs in regulatory regions rather than coding regions [149]."

"Parental stress and parental depression were significantly associated with increased risk for ADHD overall and both symptoms and diagnosis. Specifically, maternal stress and anxiety, maternal prenatal stress, maternal depression, maternal post-partum depression, and paternal depression were positively associated with ADHD. In addition, parental depression was associated with symptoms of ADHD inattentive and hyperactive/impulsive subtypes. Parental antisocial personality disorder was also positively associated with ADHD overall and specifically ADHD diagnosis. Prenatal antidepressant usage was associated with ADHD when measured dichotomously only. These findings raise the possibility that prevention strategies promoting parental mental health and addressing parental stress could have the potential for positive long-term impacts on child health, well-being, and behavioral outcomes."

"twin studies fail to separate the effects of genes and the prenatal environment. This failure casts doubt on claims of the relative effects of genes and environment on intelligence, psychiatric disorders, personality and other psychological variables, and other conditions."

"Although many twin studies have been conducted (which is quite an understatement; there are almost 9,000 hits for “twin study” on PubMed!), there have long been critics who argue that they are scientifically worthless."

"Because heritability is defined by both genetic and environmental influences, it is not a fixed characteristic of a disease or trait, but a population-specific estimate, analogous to, for example, the mean height, cholesterol level or life expectancy in a population. It also cannot be interpretated at the family or individual level."
