I want to perform a latent class analysis using poLCA package. My formula

substances <- cbind(subs1, subs2, subs3, subs4, subs5, subs6) ~

I want to include sample weights in the model, I have read that poLCA does
not take into account weights, but when I introduce them, it seems that the
model is running correctly. This is the command I am using: 

lca2 <- poLCA(substances, ena, nclass=2, graphs=TRUE, maxiter=2000,

my question is, if the results are really taking into account the weights ?
if not, how can I introduce weights into my analysis? 

Thank you for your help.
