Was marijuana growing, in South America, when the first Europeans arrived? How much difference is there between the indigenous strains that are found in the Americas? Are Colombian, Panamanian and Mexican types similar to each other? Are the strains found growing in the Caribbean similar to the strains of the Americas Mainland? Does Hawaiian have more in common with Americas strains OR East Asian varieties...? I was once told that North American Indians used weed in their PEACE PIPE rituals. Any truth to this? Cannabis hemp was an incredibly useful plant to early man. When moving to new hunting grounds I would think that a bag of seeds would have been an essential item.
