Does lysergic acid link the Salem witch trials and a Catholic saint?

The ancient Celtic festival of Samhain, first celebrated in Ireland around 2000 years ago, marked summer’s end and the winter’s beginning, eventually begetting All Hallows’ Eve. This year, Tourism Ireland launched an ad campaign proclaiming the nation as the ‘home of Halloween’. However, a return to the roots of Halloween likely won’t slow the rush to its ‘unofficial hometown’ of Salem, Massachusetts, in the US which saw over one million visitors in October 2023. Modern day Salem’s popularity as a festive fall destination is connected to the notorious witch trials of Salem Village in 1692–1693 – events that saw 200 people accused of practising witchcraft and 20 of them, mostly women, executed.
