Not from either of those two options, you could hypothethetically make heroin from poppy seeds and LSA from Hawaiian baby woodrose seeds. LSD is found in ergot which is fungus on rye bread. Ingesting that will make you very sick. I'm not sure about converting LSA to LSD but Making LSD in the first place is a very complex and costly process, I wouldn't bother.
nope you cant make acid out of em or really even trip off em, and you can buy them online just google it.
You can make poppy seed tea from unwashed poppy seeds. Sometimes it can be extremely potent. One reported case of overdose.
