What was in Popeye's can?

We are all familiar with Popeye, the loveable "spinach" eating sailor. Was that REALLY spinach in his can? We will notice Popeye would consume a leafy green substance and within seconds become quick to anger, impervious to pain and with the strength of 10 men. We all know spinach does not produce this effect. I suspect Popeye actually consumed a volatile cocktail of hashish, angel dust perhaps laced with PCP and spinach as a chaser. It should be noted that Popeye frequently injected this substance through his pipe. Also, we notice his love interest was the anorexic and possibly heroin-addicted Olive Oyle. Who was the father of her bastard child SweetPea? What happened to SweetPea in school when the kids made fun of him because of his sissy name? This was never explained in the cartoon. Many cartoons showed Bluto kidnapping Olive for the intention of getting a little "kiss". Also, one cartoon showed Poeye and Bluto living together as members of the "Woman Haters Club". Does this not imply Popeye and Bluto were having a homosexual affair? Could Popeye have been the early impetus for homosexuality, drug addiction and rape in todays youth?
