I definitely question the scientific basis for anyone saying that LSD is “extremely safe”.
I don't think it's been easy to study things considered illegal. Most research came to halt once the govt cracked down on it in the 70s. Here's a review that seems to indicate, at least by studies set to standards from several decades ago, that it appears to be pretty safe overall.
Lysergic acid diethylamide (LSD) was studied from the 1950s to the 1970s to evaluate behavioral and personality changes, as well as remission of psychiatric symptoms in various disorders. LSD was used in the treatment of anxiety, depression, psychosomatic diseases and addiction. However, most of...

Two cases of serious adverse effects were reported...
-tonic–clonic seizure, without subsequent complications, in a patient with a previous history of seizures
-prolonged psychosis was reported in a 21-year-old patient with a previous history of recurrent psychotic episodes... This patient received psychotherapy and antipsychotic medication, recovering without later complications.
-No other serious adverse effects were described in the remaining 565 subjects
More recent studies also seem to show that it's pretty safe:
No severe adverse reactions were reported in modern LSD studies (Carhart-Harris et al, 2016b; Dolder et al, 2016; Kaelen et al, 2015; Preller et al, 2017; Schmid et al, 2015).
This is consistent with the view that LSD is relatively safe when used in medical settings and according to safety guidelines (Johnson et al, 2008)
Seems that it may be safer on average than modern drugs
In the US:
-3 to 7% of all hospitalizations are due to adverse drug reactions.
-ADRs occur during 10 to 20% of hospitalizations; about 10 to 20% of these ADRs are severe
-These statistics do not include the number of ADRs that occur in ambulatory and nursing home patients
-Although the exact number of ADRs is not certain, ADRs represent a significant public health problem
As for hallucinogens overall it seems there are some promising things coming out of Hopkins and NYU.

There are also several trials going on from the commercial side. So far the results seem promising. I follow them to some degree since I'm currently invested in several of these nascent companies. Risky for sure, but anyone looking to get in on the ground floor may see an opportunity.
I don't think it's fair to determine something to be unsafe when it's illegal. If someone is concerned about getting arrested and negatively impacting their career when using a substance, it seems natural that they would have severe anxiety and paranoia if they can't control these emotions when using this substance. That wouldn't really be the fault of the substance but more so the environment of illegality surrounding it. In the right setting, these adverse psychological effects would probably not occur.
