Uncle Thundercock smoked pot his entire adolescent life during the 1960s and 70s, and when he decided to file away his partying days and join the adult world, he had no problem at all stepping away from weed. But studies from 1983 to present show that the average THC level (the chemical in pot that gives the buzz) back then was about 4%. The same group found that over the last few decades, the seized pot they studied had risen to over 10%, with some plants as high as 30% . It's predicted that in the next five to ten years, that average will reach around 15% before it hits a plateau.
Some pro-life advocates argue that it is the presence of life alone, or of unique DNA, that defines personhood. Many things that we do not consider to be living persons might meet this criterion. Our tonsils and appendices are certainly both human and alive, but we don't consider their removal as constituting anything close to the killing of a person.
The unique DNA argument is more compelling. Sperm and egg cells contain genetic material that will later form the zygote. The question of whether certain forms of gene therapy also create new persons could be raised by this definition of personhood.
