Bad Buzz

could be the particular strain(some cause anxiety more than others). also i dont know how u smoke.. but if u arent use to high grade it may just be some bomb shit dude. lol

I think you might be right. I am probably smoking way too much because I am used to lower quality. It lasts for hours too!

Some strains don't work with certain people. I haven't experienced it myself, but I hear about it frequently enough.

I'm guessing it's the genetics you got more so than the environment.

There is another factor involved and that is at what stage you harvested. Were your trichs mostly clear, mostly cloudy? The clear and cloudy will tend to give you the more head high, uplifting while the cloudier with more and more amber is more the couchlock.
Also, depending on the plant itself (didn't say where you purchased your seeds) it could be a sativa dom pheno, which would lead normally to a more uplifting heady high. There are so many different breeders and strains of Northern Lights available it would be hard to say.
So IMHO, I would say go through your check list, what stage did I cut? who was the breeder? was it indica or sativa don type of buds? This should help determine why your high wasn't what you were expecting. Quick link here for you to research your breeders strain http://en.seedfinder.eu/search.html
Good Luck finding your solution and future grows

There is some weed that does that to me, it doesn't have to be hi quality always either. I usually get a mids or danks and I can tell the difference in effects and price obviously. The truth is that some weed after takin 4-5 puffs will just make me have anxiety attacks. Other types will just set me off feeling almost euphoric and I have no stress or anxiety in the world.

I have that same problem. This is why i havent smoked in a few years. I smoked for years and never had problems....smoked a joint of some shwag and was having such bad anxiety i turned pale white and my whole body was shaking. Also had it happens with some mids during a shine down concert i ended up hyperventalating and passing out and having to be carried outside. My anxiety has gotten worse of the past few years so now i'm looking into self medicating. Northern lights would be one strain i'll be staying far away because of the type of high.
