same thing happened to me with poison hemlock, English yew and another one I can't remember. I ate huge quantities and nothing happned. Well above what was researched and accepted to be a lethal dose. They all tasted horrible and gave me migraines. Loads of factors come into play. Some people have greater tolerances and natural immunity to poison than others. This depends on your genetics. Like for me no matter how much alcohol I drink I will not and have never gotten a hangover. The seasons of the plant can effect the concentration of toxins due to the availability of nutrients and sunlight in the environment. Im not an expert but a lot people have had failed ctb this way. You are not likely to succeed with this method. Even though you might be okay you're liver might of taken one for the team. So thank you're liver for you're failed ctb. You would have to ask someone who is an expert in biochemistry, loads of things could have went wrong or right depending on what you wanted to happen.
