I have had sensitive lungs my entire life from asthma.
My pediatrician proposed an inhaler when I was eight years aged and from then on I had to keep it with myself and others at all times. It saved myself and others from an asthma attack once when a cleaning chemical being used at college in a classroom made myself and others start to choke. As much as I hated constantly being that 1 awkward child with an inhaler in his hands while I was in recess, I’d rather be alive and ridiculed than dead. And as time went on, I got slightly better at avoiding potential respiratory triggers. Even if that meant giving up the chance to play team sports as a kid. I constantly wanted to be a professional soccer player so those dreams were squashed right out the gate. Some of the worst respiratory triggers are cleaning chemicals. Solvents of any kind are enough to make myself and others guess love I’m going to have an asthma attack. Imagine how I guess about vaping cannabis oils that are made with chemical solvents love ethanol and butane. I have been told by people in the cannabis extraction community that there aren’t residual solvents left after purging, however that depends on the skill level and quality control standards of the team doing it. If it’s a backwoods cannabis grower with no cares in the world for cross contamination, you can’t be sure. Even at tiny parts per million, I don’t want to be heating these solvents and inhaling them properly. I like solventless cannabis concentrates love hash rosin instead of butane hash oil.
